The Kid Laroi's TikTok star girlfriend Katarina Deme, 18, puts on an eye-popping display in a plunging crop top at Justin Bieber's party in Los Angeles
She celebrated her 18th birthday last month at a trendy bar in Los Angeles.
And the partying continued for Katarina Deme on Tuesday as she accompanied her rapper boyfriend The Kid Laroi to a star-studded bash at West Hollywood celebrity hotspot The Nice Guy.
The model and TikTok star turned heads as she arrived at the venue with Laroi, whose real name is Charlton Howard, for a concert after-party hosted by Justin Bieber.

Justin and Laroi are good friends and collaborated last year on the No. 1 hit Stay. The Canadian singer's model wife Hayley Bieber is also believed to be pals with Katarina.
Katarina looked stylish on the night in a plunging crop top that drew attention to her ample assets, and completed her ensemble with flared jeans and Doc Martens shoes.
Meanwhile, shaggy-haired Laroi, also 18, showed off his fashion credentials in an embossed blazer, printed T-shirt and black pants.

The couple joined a slew of stars including Jaden Smith, singer Tinashe and Justin himself at the party following his latest concert at the Crypto.com Arena.
It comes after Laroi threw Katarina a surprise birthday party at a restaurant in LA on February 19, inviting all her friends and family.
The American socialite couldn't quite believe it when she entered the venue with her boyfriend and saw the assembled guests.
She clearly wasn't expecting a party, and almost immediately broke down in tears.

'The best surprise ever. I've always cried on my birthday, but this was the first time from just being happy,' she said on Instagram.
The couple have been dating for more than a year.
As his personal life goes from strength to strength, the Without You star has been concentrating on his career of late.
In November, he announced he was taking time out to work on his first album.

Laroi explained that after a 'wild year' he was focusing on his full-length release.
He thanked fans for supporting his debut mixtape, F*ck Love, but said he needed a digital detox to optimise his creativity.
'My life has changed so much this past year because of [F*ck Love] and I owe it all to every single one of you. There is no way I will ever be able to repay you,' he said.
Relaxed: Laroi and Katarina are pictured on vacation last year
'Last week I went on a small vacation for the first time in a while. During that time I started thinking and I made the decision that I need to take some time away from everything and focus on the next project: my debut album.'
Laroi promised fans he would be back soon.
'I'm going to miss you all beyond words can describe, but I do believe that this is what I need to do to give you all the best music possible,' he concluded.
