X17 spotted Brody Jenner at The Roosevelt Hotel in Hollywood Saturday night -- but Brody looked like he wasn't feeling so hot.

Sources tell us that Jenner was hit with a bottle after a nasty bar brawl that went down inside the hotel's nightclub.

The son of Bruce Jenner had been trying to break up a fight between girlfriend Avril Lavigne and another Roosevelt patron, and got whacked in the scuffle.

Police were called and Jenner spent the early morning hours in the hospital. He Tweeted around 7 a.m. PST on Sunday morning: "Interesting Saturday night... Just got of the hospital with a new scar on my face.. Charges/chargers!!!"

The night didn't start off as badly. He Tweeted while partying at the hotel, "Having the best night with the love of my life @AvrilLavigne so happy right now!!" By the time police arrived, Lavigne had split.
