Britney Spears is back at her favorite vacation spot: Maui! The 38-year-old pop star is enjoying an early birthday getaway with her boyfriend, Sam Asghari, 26, and they traveled out to the west side of the tropical island for a cliff jumping adventure amid the trip. Britney shared an Instagram clip of their nature outing on Nov. 18, which showed her and Sam making their way down a cliffside path before leaping off rocks and into the sparkling turquoise water.
