Selena Gomez continues to celebrate her 21st Birthday in Malibu, and Bieber showed up at midnight bearing a rose.
E! News exclusively reports Gomez and about five girlfriends kicked off their evening with dinner at Boa.
Kellan Lutz and Nicole Scherzinger were also at the night club, with the source adding, "Everyone ended up interacting and having a great time."
On the night of her actual birthday Monday (the same day the royal baby was born!), Gomez kicked off the festivities with an intimate private dinner with family and friends at Bagatelle restaurant.
The next day, she appeared on the Tonight Show and told Jay Leno she "had a shot of Jack [Daniels]" when he asked which drink she sipped to ring in her milestone birthday.
She had a party in Malibu last night where Justin Bieber reportedly showed up at midnight bearing a single rose as a gift.
