Funny or Die has up an amusing clip starring a group of television and movie stars including Alyson Hannigan, Emily Deschanel, Kat McPhee, Minka Kelly and Jaime King in which they are at a slumber party together. One of them feels a lump on her breast and starts to panic. The issue gets resolved but not before the paparazzi show up to get some rather embarrassing photos of the group.

The sketch was co-written by King and Taryn Southern and is sponsored by Her Energy in support of breast cancer research. The entire six-part series is called "Tit for Tat." Let's hear it for amusing double-entendres.

Still, it's for a good cause and stars a plethora of television personalities (including the ever-cute Ms. Hannigan whom I've adored since her days on Buffy the Vampire Slayer), so it's worth a look even if you're just a perv who likes watching female celebrities grope each other. Video is after the jump.

Thanks to Tyra Banks -- supermodel, talk show host, and self-appointed "Boob Tester" -- we now have official confirmation that Katharine McPhee's breasts are real. And thanks to The Tyra Banks Show, we also have video confirmation, as well.

Honestly, I'm just wondering when women became so damn grabby? First photos surface showing Idol semifinalist Antonella Barba cupping a girlfriend's naked breast. And now we get to watch as Tyra grabs and shakes Katharine's tatas like they're couple of fresh melons at the Acme Supermarket.

As part of February sweeps, last year's American Idol runner-up Katharine McPhee is going to guest-star on Ugly Betty. McPhee will be playing herself, a celebrity guest at Mode's Fashion Week runway show, in an episode entitled "I'm Coming Out". No word yet on whether or not this hour will be Justin-centric... Oh, c'mon, don't tell me I was the only one that read the title and immediately thought of him.

McPhee's appearance will air February 1 (8:00 PM EST). Hmm... Sounds like ABC wants a little bit of FOX's American Idol glow. Also, McPhee is probably doing this to promote her self-titled debut album, which drops later this month.
