Justin Bieber's Rumored GF Had A Seriously Dramatic 18th Birthday Party


In case you didn't realize -- it's Sofia Richie's birthday week (she's been banging on about it for ages).

The celebrations finally happened Wednesday night, and boy did they look swag.

She went to The Nice Guy in Los Angeles in an awesome pair of Adidas pants.

There was food:

Outrageously big sparklers:


And fire fashion:

Later on that night she was pictured laughing and yelling outside the club -- reportedly at a group of photographers who had fallen over while trying to take a snap of her.

There was no sign of rumored boyfriend Justin Bieber.

They're keeping their relationship seriously low key.

But the other day Sofia was spotted leaving his Toluca Lake mansion.

We don't know what these guys got up to, but later on that day Sofia paid a visit to the doctor's office.

She posted a picture on Snapchat and wrote,


But obviously she powered through and managed to celebrate a swag b-day.

Congrats on the big 1-8, gurl!
