BAACK ON? Karrueche Tran CHEERS ON Chris Brown At Jhene Aiko's Concert, Chris TWEETS "She Look Amazing..."

Will Chris and Karrueche be back in one another's embrace by Christmas? We suspect so. Find out why inside...

Just a few days ago, we witnessed Chris embark on a super nasty "takedown" of Kae on social media, which he promptly apologized for. We thought she had smartened up with her posts about FINALLYleaving. Now, he's being flirty again. SMH....

Two incidents went down this week. First, both Chris and Kae were spotted at Pinz Bowling Center with their friends two nights ago. They weren't photographed together, but both "Checked in" via Instagram. Coincidence? Maybe.

Then, Kae and her friends went to see Kae's homie Jhene Aiko at the Nokia in LA last night (above) and Chris was on the bill. He hit the stage to perform "Drunk Texting." Coincidence? Maybe.

Spies report that the two met up for a late-night conversation after the concert as well. Coincidence? Maybe. Then this tweet appeared (and was deleted per usual) from Chris' Twitter timeline. Way too many coincidences.
