Avril Lavigne & Ryan Cabrera Are Friends Who Kiss & Cuddle

Avril Lavigne and Ryan Cabrera had the most romantic steak dinner you've ever seen 2 "friends" have.

The duo was spotted Tuesday night at STK Midtown in NYC, sipping rosé and chowing down on filet and foie gras. Witnesses say they were cozy, cuddly and even kissed a few times.

Avril's been adamant they're just pals. As we reported, Ryan moved in with Avril after she ended things with Chad Kroeger -- but only because his GF kicked him out. That's what friends are for, right?
