In honor of tonight's True Life (True Life: I'm Having Twins), we thought we'd round up a list of Hollywood's most famous birthday-sharing siblings. But after a few minutes of brainstorming, we realized that wasn't as easy as it sounds. Sure, we've all heard of the Olsens, The Veronicas and Good Charlotte brothers Benji and Joel Madden. But most of the twins we dug up were celebs with nonfamous twinsies (like Jon Heder, Ashton Kutcher and Alanis Morissette)!

+ Think you can come up with any famous pairs (Jason and Jeremy London, Tia and Tamara Mowry) that we forgot? Tell us your fave twosome (ours is still Arnold Schwarzenegger and Danny DeVito!) then read up on all the celebs mommies who are seeing double.

In Touch mag claims Britney Spears has been dating the ex-boyfriend of her former gal pal, Paris Hilton! According to the tabloid, Brit and Good Charlotte rocker Benji Madden have "been on a few dates" and really seem to like each other.

So how'd the two (alleged) lovebirds meet?

Reportedly, Spears manager "made some phone calls" to potential suitors (including Chace Crawford and Michael Phelps!) and Benji "ended up being the most interested."

We'd say something snarky, but we think we just vomited a little bit in our mouths. Allegedly.

UPDATE: Britney Spears' publicist, Holly Shakoor, barks back with a full denial. "The claims made by In Touch are completely false," she tells E! News. "There is not an ounce of truth to any of it."

Lunch Roll Call Time!
Audrina? Check.
Lauren? Check.
Frankie? Maybe.
Nicole Richie? HUH?!

Sure, Nicole Richie may be an expectant Mom with Good Charlotte's Joel Madden, but did you expect these two to share an ex-boyfriend (Brody Jenner) let alone a leisurely lunch?

So this week we leave it up to you. Caption this picture!
