It's been just over a year since Troy Aikman got divorced ... but it seems the NFL legend is back in the game ... with a smokin' hot mystery blonde.
Troy and his P.Y.T. hit up Boa on Sunset Blvd. Monday night ... where Troy and his special friend were confronted by the dreaded ROSE LADY!!! Of course, Aikman handled the situation like a pro.
So far, no word on how they met, who she is, are they official, etc.
TMZ broke the story ... Troy quietly divorced former Dallas Cowboys publicist Rhonda Worthey back in April after more than a decade together.
11:25 AM PDT -- We're told the woman is Abigail Klein -- an ex-Cowboys cheerleader. One source tells us the two are "just friends."
