Selena Gomez didn't mess around when it came to celebrating her 21st birthday.
During an appearance on Tuesday's Tonight Show, host Jay Leno asked the "Come & Get It" singer about her first legal drink upon reaching the milestone.
"I had a shot of Jack [Daniels]," Gomez revealed.
When Leno inquired how many, she admitted, "I don't remember."
The star added she was "a little bit" hungover the next day, but noted "it was fun."
Gomez also told Leno she will continue to celebrate her birthday this weekend with a "gypsy-themed" party.
On Monday, her actual birthday, the gal enjoyed an intimate meal with family and friends at L.A.'s Bagatelle restaurant.
"The party was great," a source told E! News. "They did a private dinner for about 20 people, all close family and friends. She was in great spirits and all smiles all night. Ashley Benson [Gomez's Spring Breakers costar] and Francia Raisa joined her for the night."
Can't wait to see what 22 brings!
