Britney Spears looked phenomenal as she enjoyed a tropical honeymoon with her model husband Sam Asghari, following their wedding in June.

The "Gimmie More" hitmaker, 40, posted a sizzling video to her Instagram on Independence Day as she frolicked on the beach in a neon and tiger print bikini that showed off her toned body.

The video appears to have been taken by her husband, whose shadow could be seen throughout.

Britney appeared to be having a great time and had a bright smile on the ocean waves in the clip, which was accompanied by Justin Bieber's hit song "Honest".

Although it's unclear how long Britney has been on her honeymoon, she began her post by describing what she's been up to while the weather hasn't been ideal.

Before posting the sultry clip, she shared a video of her third husband as they traveled with their Australian Shepherd dog, named Saëyer, on a private jet - presumably to their honeymoon destination.

The couple tied the knot in a lavish ceremony in Los Angeles last month, with celebrity wedding guests including Paris Hilton, Selena Gomez, Drew Barrymore, Donatella Versace and Madonna,

DailyMail writes.

They also recently moved into a new luxury mansion, explaining that she and Sam had been focusing on buying their new home before planning a honeymoon.

Spears was previously married to Kevin Federline, 44, from 2004 to 2007. The two have two sons, Sean Preston Federline, 16, and Jayden Federline, 15.

She was also briefly married to childhood friend Jason Allen Alexander in 2004, before it was annulled.

Alexander tried to stop her marriage to Sam, but ended up being arrested by the police.
