(S05E11) Tom opened the results show by noting that this week of Dancing With The Stars was meant to be sexy, but ended up being full of drama. I was disappointed that the footage of Marie fainting was shown again (and again and again). Nothing terrible happened to Marie, but does that justify playing the footage several times more? I thought it was insensitive. Tom added a teaser for the Jennifer Lopez performance (for which I was totally psyched), and warned viewers that "nothing can be taken for granted."

As usual, Monday's performances were summarized. Mark set out to entertain, but didn't impress the judges. Jane was thrilled to be compared to Edyta, who is only in her 20's. Cameron was pleased with the intense chemistry that he had with Edyta. Jennie joked that while she might not have Bruno's support, Len was on her side. Sabrina's hot and heavy Rumba earned her another ten. Helio had a setback, but tried to laugh off Len's dentist comment. Maks dorked out about getting to meet the Spice Girls. Marie's collapse was saved for last, and additional footage from during the commercial break was shown. Not cool. In an interview, Marie explained that she occasionally gets winded and passes out in response to stress. She was an amazingly good sport about all of it. I saw a promo for Entertainment Tonight, and they actually made her watch it again on-camera. Morbid much?

The leaderboard read as follows: Marie Osmond and Mark Cuban were tied for 7th, with 21 points; Helio Castroneves was in 6th place, with 23 points (his lowest score so far); Jennie Garth came in 5th, with 25; Cameron Mathison and Jane Seymour tied for 3rd, with 26 points; Sabrina Bryan was a close second, with 28 points; finally, Melanie Brown was in the lead (for the first time ever) with 29.

Len remarked that this season was "topsy-turvy," since the same couple had never performed the encore twice. Melanie and Maks' Samba was picked this week. This was one of the few instances this season where the highest-scoring couple was tapped for the encore. The couple's spicy Samba went off without a hitch.

For her first performance, Jennifer Lopez performed "Do It Well" from her new album, Brave. J-Lo was accompanied by several of her own back-up dancers. The routine featured mostly hip-hop moves, and it really got the crowd going. Baby bump watchers didn't get much luck; Lopez was draped in some sort of poncho-type outfit. She even got out on the dance floor and did some of her old fly girl moves.

After the musical number, the audience got to sound off on Week 5. Alfonso Ribeiro (can we please get him to do the Carlton Banks in Season 6?) and Heather Mills were both scared during Marie's fainting spell. Like a lot of the audience members, Heather thought it was a joke at first. Some audience members were underwhelmed by Helio's routine. Florence Henderson thought that Jennie was terrific, as did Tori Spelling. Tori made a good point at the end of the segment--if someone like Mel can wind up in the bottom two, it's anyone's game.

The first phase of the elimination round put Sabrina and Mark on the safe list, along with Melanie and Maksim. I was sure that Marie would be let off the hook first, after her scare on Monday night. Her absence from the safe group had me worried at first.

Backstage, Samantha discussed the fainting incident with Marie. Marie handled the questions well, taking time to thank her fans for the concerned e-mails. Samantha observed that Helio and Julianne's scores were declining, and wondered aloud if they were going in the wrong direction. Great investigative journalism there, Samantha. Helio joked that race car drivers only go to the left.

Next week's group routine will be choreographed by Christian Perry, who performed his own group number this week. The rock and roll performance ("Dance, Dance" by Fallout Boy) looked like an extreme, modern take on swing. It was astounding--those flips and lifts were really impressive.

Jennifer Lopez sang "Let's Get Loud" (from On the 6) for her second performance. She was joined by 8 of the show's professionals, including Alec, Derek, Julianne, Karina, Mark, Edyta, and Cheryl (I didn't catch who the fourth male was). This was easily my favorite musical performance of the season, and possibly all the seasons combined. The pros did an incredible job as well.

Speaking of the pros, the professional cast got to weigh in on the difficulties of choreographing routines each week. Julianne called the process life-consuming. Edyta said that she listens to the music at least 50 times before choreographing, and Maksim does the choreography on the fly with Mel during practices. Derek emphasized the importance of taking risks. Kym said that she choreographs to show off her partner's strengths and hide his weaknesses. Maks proudly mentioned that his choreography centers around the relationship between the man and the woman, as opposed to stunt moves.

In the second part of the elimination, Cameron and Edyta were declared safe. The camera cut to a sad-looking Marie.

After a forgettable set of backstage interviews, a segment about training and day jobs was shown. I actually liked this topic, since scheduling and priorities keep being mentioned this year. Everybody's holding down several responsibilities: Helio is racing, Mel is starting her Spice Girls tour, Sabrina is performing regularly, Marie has a new album, Cameron has his soap, Mark is managing his empire, Jane is painting and acting, and Jennie is raising three daughters. Cameron admits that if anyone slacks off now, they will be out of the competition soon. Each performer believes that they have an edge over the the other dancers.

Next, Jennie and Mark were singled out by the hosts. Jennie was put on the safe list after a long pause; Mark and Kym were in the bottom two. There was another cut to a worried Marie Osmond, which had me extra-worried. Following the break, Marie and Jonathan were finally declared safe. Shame on the show for keeping those two in suspense so long! Helio and Julianne were safe as well, which put Jane and Tony in the bottom two. Say what?

Len followed up Bruno's honesty last week by stating outright that he preferred Jane's class and elegance to Mark's entertainment factor. As many of you predicted, Mark and Kym were sent home. Mark admitted to having lost 30 pounds as a result of doing the show (kudos) and gave the cast, crew, and judges heartfelt thanks.

Now that Mark is gone, I'm seriously concerned for my favorite couples. Anyone could end up in the bottom two next week, and any of the remaining couples could make it to the finals. Sabrina is the only dancer who hasn't had a major setback so far. Everyone else has either been in the bottom two or had some significantly low scores. It's her competition to lose. Who do you think will dance their way into the finals?

Brett will be back next week for the couples and group dances. Until then, check out AOL's extensive Dancing With The Stars coverage, which includes photo galleries, a live chat (Mondays & Tuesdays, 7:30pm ET), and the chance to support your favorite couple by voting in AOL's poll!
