Britney Spears is celebrating her 40th birthday by jetting off with her fiancé Sam Asghari

She wrote on Instagram: "Oh the precious joy today!!! Me and my fiancé are so excited to be going away …. as you can see I’m not 800 pounds like the paps have me in pics. I’ve been working out and it’s real … whatever!!! God thank you for being able to go out of the country !!!! I am blessed !!!! (sic)”

Sam also took to his Instagram to share the photos to his 2.3 million followers, where he heaped praise on his wife-to-be as they celebrated.

He wrote: "I call you Lioness because I admire your relentless strength, I’m inspired by your beautiful heart, I celebrate your smile that lights up my world. Everyday is your birthday my queen Happy 1st birthday to my wife #dec2nd", before ruling out speculation that the pair have already married by noting in the comments: "I also been calling her wife since day 1" (sic) It comes just weeks after the 'Toxic' singer was freed from her conservatorship, which had been put in place back in 2007, meaning that she finally has control over her assets.

A source recently said: "She needs some time to get used to her new way of living. She is adjusting to her new existence."
