We learned a lot this week. We finally saw how much jibberish the 'Real Housewives' can yell before Andy Cohen reached his breaking point. Jessica Alba learned that she can indeed have sex while pregnant. Gene Simmons learned the hard way that in order to propose to your long-time girlfriend, you must not be so exhausted that you can't form coherent sentences. Lady Gaga confirmed that a 'So You Think You Can Dance' contestant is actually talented. And Kat Von D taught us all the valuable lesson that it might not be the best idea to get a tattoo of Jesse James's face. Check out the clips after the jump, and vote for your favorite in our weekly poll.

Jessica Alba is late in her pregnancy, so she took the opportunity to talk to renowned sex educator Sue Johanson on 'The Tonight Show' (Weeknights, 11:35PM ET on NBC). Her concern was one shared by many couples during pregnancy.

"As someone who's in the later stage of pregnancy, is there any way to harm the baby during intercourse?" Alba asked.

"That baby is in there and that baby ain't going nowhere until it's ready," Johanson assured her. "That uterus wall is just like that," she said knocking the arm of her chair. She then painted a picture of the cervix smiling from intercourse and things got a little weird.

After six seasons, Oxygen is shutting down Talk Sex with Sue Johanson. Her final advice on love, lust and awkward positions will be dispensed this Sunday, May 11. The show will feature the year's top ten sex toys. Wheee!

A frequent guest on talk shows (and a favorite of David Letterman's), the 78-year-old grandma of two has been dishing sex advice on Oxygen for six seasons. Whenever I've stumbled across the show, I always thought it was just so weird. Like getting sex advice from your grandma.

Then again, between Johanson and Dr. Ruth, maybe they make the best sexperts because you'd never look at them in a lustful way. That's just my armchair psychology talking.
