Sam Asghari congratulates ‘lioness’ Britney Spears on 40th birthday: ‘I’m inspired by your beautiful heart’

Britney Spears‘s fiance Sam Asghari paid tribute to the pop star on her 40th birthday.

The personal trainer and actor, 27, shared a touching message from his Instagram account in which he praised Spears’ “relentless strength” and “beautiful heart”.

“I call you Lion because I admire your unwavering strength, I am inspired by your beautiful heart, I honor your smile that lit up my world,” he wrote.

“Every day is your birthday, my queen. Happy 1st birthday to my wife. ”

Asghari and Spears met in October 2016 on the set of her “Slumber Party” music video, in which he starred as her lover.

Spears announced her engagement in September of this year, in a video posted to Instagram.

In the video, the “Toxic” singer shows off a 4-carat diamond ring engraved with the word “lioness” – Asghari’s nickname for Spears.

It also shows Spears winking, kissing and smiling at her fiancé and responding “Yes!” when he asked her if she liked the ring.

The 39-year-old captioned the post on Sunday night: “I can’t believe it.”

Asghari was praised for assisting Spears in her protection battle, ended when the legal agreement formally ended earlier this month.
