Odell Beckham Jr. celebrated the Rams' win on Sunday in style ... hitting up an L.A. hotspot just hours after he and his team punched their ticket to Super Bowl LVI.
The star receiver arrived at Delilah in West Hollywood shortly after beating the San Francisco 49ers at SoFi Stadium ... and he came sportin' his fresh NFC Championship hat.
Odell also rocked a big chain for the occasion ... and then he rubbed elbows with some celebs at the venue.
Travis Scott was there, and so was Tyga, who actually had celebrated with OBJ on the field following the big win earlier in the day.
