They could change the show’s name from Dancing With the Stars to Flirting With the Stars — and Derek Hough would still be the reigning champion!

Hollywood is always a hotbed of gossip about hot young things hooking up, and "multiple sources" told Us Weekly that Derek had a little hook-up with Twilight star Nikki Reed — who recently split from her husband, American Idol alum Paul McDonald.

A witness told the magazine that Derek, 28, and Nikki, 25, were making out on April 18 at Rock & Reilly's in L.A., where they were joined by fellow DWTS stars Mark Ballas and Cheryl Burke. Nikki and Derek had "lots of PDA," the witness said, including hand-holding, and they left together.

Nikki is a friend of Derek's sister Julianne Hough, and you may recall Derek dating another one of Jules' buddies, The Vampire Diaries’ Nina Dobrev. (He does seem to like brunettes...) That has to be one of the benefits of having a cute sister — they tend to have cute friends too.

But no one is suggesting that Nikki and Derek are a serious couple, or even dating — not yet, anyway — just that they got a little extra flirty. "Nikki and Julianne are good friends," a source said, "and she has hung out with Derek a few times through her. They're having fun but it's nothing serious." Apparently they are still close, though, since the source said Nikki was hanging out with Mark's girlfriend BC Jean backstage after the April 29 DWTS show.

Nikki did just get out of a two-year marriage, so it's no surprise she wouldn't want to jump back into anything serious. But she's a lucky lady to be spending any time at all with both of the Houghs!

DWTS Season 18 airs Mondays at 8 p.m. ET on ABC.
