Are Kim Kardashian and Miles Austin rekindling their romance?

The exes exchanged friendly, flirty Tweets on Wednesday, sparking talk of a potential reunion.

Dallas Cowboy Austin, 26, paraphrased his ex girlfriend, Tweeting, "Sometimes u have to fall down to know where u stand."

Kardashian, 30, Tweeted back: "Those are some pretty wise words ;-)."

Retorted Austin: "Yea, I stole your quote!"

The reality starlet then Tweeted a polite correction: "And the quote really goes 'sometimes it takes a good fall to know where you stand' [Cite] your source!"

Austin's not the only guy in Kardashian's life at the moment, however. She's "been out a couple times" in NYC and L.A. with quirky musician (and ex to Jessica Simpson and Jen Aniston) John Mayer, a pal tells the new Us Weekly.

Explains another friend: "They have been friends for years."
