Sam Asghari Shows Massive Fireworks For Britney Spears' 40th Birthday!

It's Britney Spears' 40th birthday, and we can't seem to keep calm, and neither can her fiancé Sam Asghari! The Princess of Pop turned the big 4-0 today, December 2, and Asghari is proving to be the ultimate lover boy.

In a recent Instagram story update, Asghari showed off the massive fireworks he arranged to celebrate Britney's birthday.

The elaborate display contained various colors, including gold, red, blue, purple, green, and yellow. The fitness instructor spent big bucks on the fireworks display, which continued for quite a while as he silently filmed. Finally, he simply and sweetly captioned the video, "Happy Birthday."

Hours before the fireworks display, Asghari surprised the "Toxic" singer with a giant cake while onboard a private jet. The personal trainer presented Britney with a B-shaped cake featuring elaborate rose decorations while singing Happy Birthday.

A thrilled Britney in the background gushed, "oh my God! it's a beautiful B! Oh my God thank you so much!" The doting fiancé then added a cute mini bouquet which Britney described as "so nice."

Asghari promised that the B-shaped cake was the "first of many cakes," after which the lovebirds put on an intense display of PDA.

Britney, who looked dashing in distressed daisy dukes paired with a simple white shirt and killer red boots, flaunted her pert derriere to the camera s Asghari fondly grabbed it.

The lovely couple locked lips intensely before giving the camera a thumbs up. Asghari then paid tribute to his queen for the special milestone in a separate Instagram upload of their loved-up moment. 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.

The bubbling celebrant shared the same picture to her page and, in her caption, gushed about the "precious joy" she was experiencing. Britney expressed her immense happiness at being free on her birthday. "God thank you for being able to go out of the country !!!! I am blessed," she wrote.

She also touched on her banging physique, revealing to fans that she has been "working out and it's real."

Hours before the birthday celebration began, the Grammy Award winner called out the paparazzi after releasing a photo of her coming out of a public bathroom. Britney revealed in a post that she "had a sh---y day yesterday" because of the incident but managed to get her groove back on.

True to her nature, she danced the pain away to Madonna's "Vogue" while detailing her impressive "Party For Confidence" guidelines. Britney showed off several glamorous dresses and urged her fans to do the PFC to build their confidence.
