The 24-year-old actress was caught cozying up to her very own Magic Mike(ish) man at the El Lay premiere screening of Lee Daniels' The Butler!
That's the second time these former flames have been seen out together in the past few weeks!
"There was definitely warmth between Riley and Alex. They were laughing together and smiling at each other. They definitely came together."
The observer added that Riles was wearing some bling on her left ring finger, but we find that hard to believe since there's no pictured evidence!
The stars were once engaged in early 2012, but broke off the pending nuptials before the year was up!
Although the beauty and RPatz have been rumored to be hooking up, Riley is slaying the dating rumors by very publicly outing that her and Alex are somewhat back on!
Get yo' date on girl!
