Britney Spears gives her boyfriend a smooch in a cute new photo. The 36-year-old singer shared a sweet moment with Sam Asghari during a beach day Thursday ahead of her 37th birthday. The picture shows Spears kissing Asghari on the cheek as her beau takes the selfie. Spears wore a blue animal print bikini, while Asghari went shirtless. "@samasghari," Spears captioned the post, adding three pink bow emojis. Asghari posted the same picture on his own account. "Guess whose birthday is coming up? #princess," he wrote. Spears will turn 37 years old Sunday. She and Asghari started dating after meeting on the set of her "Slumber Party" music video, which debuted in November 2016. "I've been with this man for over a year... everyday he inspires me to be a better person and that makes me feel like the luckiest girl in the world!" Spears gushed on Instagram in February. Spears will kick off her Domination residency show at the Park MGM in Las Vegas in February. She completed her first residency, Piece of Me, at Planet Hollywood in December 2017.
