The two were reportedly there for hours drinking while Avril chose to go for the vodka tonic and Brody for some beer.
Witnesses even caught the two kissing a few times and holding hands throughout the night.
As for Avril, apparently she was too tipsy to remember to tie her shoelaces as she almost tripped on them on the way out of the club.
But the oddest part of all, Brody's mother Linda Thompson was there with them. And when the trio got in the car, Avril was even spotted SMILING and getting a hug from Linda.
Wonder how long these two will last.
