Karrueche Tran was spotted out last night with her ex Quavo

Karrueche Tran and her ex-boyfriend Quavo were spotted out together last night in Los Angeles - at Travis Scott's Christmas party.

Karrueche and Quavo were both invited, and the two spent a lot of time talking and laughing together in the parties VIP area.

Then, they left just a few minutes apart. It's not clear whether they planned on continuing the evening together - away from the cameras and the crowds.

This is an interesting development, because Karrueche is currently dating NFL analyst Victor Cruz. Karrueche and Victor have gotten very serious over the last year, and we hear that they are even talking marriage.

But while Karrueche was with Quavo, Victor was in Aspen last night:

Here are pics of the two leaving Travis' party last night.

Quavo wore an extra casual outfit, as usual. The Migos rapper was covered from teeth to toe in massive bling.

The rapper smiled wide for photographers and held his hands up to show off all of jewelry as he made a very fashionable exit from the party. Looks like he's been a good boy this year.

TMZ caught up with Kae earlier this week and she said: Travis Scott is making a HUGE MISTAKE by doing the Super Bowl halftime show with Maroon 5 ... and now she's hoping and praying he back out ASAP.

"I just don't think it's a good idea," Tran told us outside Hyde on the Sunset Strip ... "I'm really hoping it's not gonna happen."

Seems Tran -- who's dating ex-NFL star Victor Cruz -- is unhappy with the way the league is treating players like Colin Kaepernick. She also seems to be unhappy with the way the league is handling violence toward women.

Amy Schumer has called for celebrities to boycott the NFL and the halftime show -- and Tran clearly agrees.
