Selena Gomez is celebrating her 21st birthday to the max. It was learned that before the Spring Breakers star has her big gypsy-themed blowout bash in honor of her big 21, she also got her party on last night in Los Angeles. Gomez and about five girlfriends kicked off their evening with dinner at Boa restaurant, and then took a quick walk across the street to John Terzian’s Bootsy Bellows nightclub. Once inside, the “Come & Get It” crooner and her crew were given a table in the front room and stayed until closing, dancing to music spun by DJ Devin Lucien. Gomez’s Spring Breakers co-star Ashley Benson and Ashley Greene also joined in on the celebration when they arrived at the hot spot a short time later. Kellan Lutz and Nicole Scherzinger were also at the night club, with the source adding, “Everyone ended up interacting and having a great time.” This is just the latest of Gomez’s birthday celebrations. 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. Earlier that day, she posted a photo on Instagram of her and a big group of friends partying in birthday hats, with the caption, “Guess what… I’m 21. UM, #turnupNOW.” 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. The starlet added that she was “a little bit” hung over the next day, but “it was fun.” Happy Birthday, indeed.
