Ariana Grande and Big Sean Reunite in L.A. – TMZ

EXCLUSIVE

Ariana Grande and Big Sean got their #ThrowbackThursday started a little early … with a snuggle session in his car.

The exes were cozied up in Sean’s car Wednesday night outside a recording studio in Los Angeles. For the record, Ariana was at the studio first, Big Sean showed up after … and she came outside for the reunion.

Ariana showed off one of her pooches to her ex-bae … great excuse to get closer. BTW, they left together in his ride.  

You’ll recall … Ariana and Big Sean dated for almost a year before she pulled the plug on the relationship in April 2015. She claimed the rapper embarrassed her with his “billion dollar p***y” lyric.  

They both eventually moved on — Big Sean with Jhene Aiko … but it appears old flames die hard.

Fast forward to last winter … Ariana dropped her “Thank U, Next” song. The opening lyric goes, “Thought I’d end up with Sean but he wasn’t a match.”

But, in the music vid, her “Burn Book” shows she’s still got it bad for Sean … writing Sean’s “so cute, so sweet” and “(could still get it).”

And, almost 3 months later … it looks like Sean’s getting it.
