Sofia Richie is ready to celebrate her 18th birthday—but first, there's just one thing standing in her way.
Before boogieing the night away Tuesday, the aspiring model and half sister to Nicole Richie had to press pause on the early festivities to deal with a minor delay.
"Of course I'm sick day before my birthday...Anything else want to go wrong?" she plead on Snapchat along with a photo of what appears to be a doctor's office. As the song goes, Sofia, "It's my party and I'll cry if I want to!"
Not to fret, the birthday girl recovered and headed out on the town for a private bash in her honor at 1OAK in California early Wednesday morning. A club goer exclusively told E! that Richie was joined by friends including Ty Dolla Sign and family. However, her famous dad Lionel Richie and sister Nicole did not attend.
After midnight, Sofia jumped on the mic and announced it was her birthday. She was presented with a cake in the shape of a Range Rover. Richie appeared happy and it was obvious she was having a great time celebrating her birthday. Kent Jones sang "Happy Birthday" and Richie was seen singing along to his hit single "Don't Mind."
Unfortunately, there were two special people missing from the celebration—the first was her 22-year-old brother Miles Richie. "Words don't describe how much I miss my bob. 18 doesn't feel right without you," she penned on Instagram along with a photo of the two posing in front of a mirror.
"Thank you for never turning your back on me and always being my rock. Come home so I can have a hug and feel right again. So blessed to have someone like you in my life."
The second was her rumored beau Justin Bieber. While Sofia got up and danced when his hit song "Sorry" played, Bieber was not spotted at the festivities.
While the birthday teen didn't mention any other underlying issues with the evening, the celebration comes on the heels of a social media uproar involving Bieber and his former ladies, Selena Gomez and Hailey Baldwin.
After Richie began popping up in photos with the Grammy winner, his fans went on the social media attack. "I'm gonna make my Instagram private if you guys don't stop the hate this is getting out of hand," he wrote on Instagram.
Meanwhile, Gomez chimed in to stand up for his followers. "If you can't handle the hate then stop posting pictures of your girlfriend lol – it should be special between you two only," she commented. "Don't be mad at your fans. They love you."
After some digital sparring between the two exes, Bieber deleted his Instagram altogether while Selena backtracked on her remarks. "What I said was selfish and pointless," she later wrote on Snapchat.
As for Baldwin, she issued this cryptic message. "Misplacing the blame onto someone else isn't going to get you to the next stage in life. so try not to manipulate a situation to make yourself look better." However, she subsequently deleted the Instagram post and clarified on Twitter, writing "The only thing I 'weigh in on' is everyday life in general. Don't rope me into things I'm not a part of and please respect my privacy."
While a source previously told E! News Richie and Bieber are not dating, their further sightings together have only fueled speculation. However, he was also sighted alongside model Bronte Blampied in the United Kingdom in recent days.
As the romance rumors continue to swirl, Sofia is ready to forge into her new year with a brand new 'do. "Yup we chopped it," she announced on Instagram with a photo of her shoulder-length bob.
Happy Birthday, Sofia!
