The first Jennifer Lopez dating rumors after her split from Marc Anthony suggested she'd cozied up with dreamy actor Bradley Cooper, but turns out they're just friends. Now, insiders say she's been dating dancer Casper Smart for a few weeks. He's "popular with the ladies because he goes shirtless," says a source (via Us magazine).

Casper Smart (via Amck.tv) Smart has had dancing roles in flicks such as Honey 2 and Step Up 3D and most recently was one of the judge's dancers on American Idol. Smart tweeted Friday: "In San Fran about his the stage with JLO! [With] JLO and the dope JLO dancers. LEGGO!"

So, we know they at least know each other, but, of course, there's no confirmation that they're actually dating. You might be able to count the fact that they were spotted out together in NYC earlier this month as semi-legitimate evidence...

We're hesitant to call this a budding relationship, and even sources say there's "nothing serious" between the two, but we are glad to hear the star is getting back out there in the dating game. We're just hoping she doesn't go off any marry him right away like she did with the last backup dancer. J.Lo and Cris Judd dated for just a few months before getting hitched in September 2001. They divorced the following June.

Twitter has given celebrities a license to unleash whatever pops into their heads upon the entire world. Many times, these off-the-cuff thoughts are self-serving or even mundane, but then there are those occasions where we get tweets that are hilarious, insane, or just downright ridiculous. Let's take a look at some celebrity tweets that made us go, "Say what?"

The best thing we saw on Twitter this week is pictured above--Oprah walking over hot coals with the motivational aid of one Tony Robbins. Thank you, Oprah, for that face:
