Cardi B is turning 28 years old on Sunday, October, 11 and she got an early birthday present from a mysterious someone.

The rapper took to Instagram on Friday (Oct. 9) to share a huge billboard that features a photo of her and two-year-old daughter Kulture matching in pink outfits. "Happy Birthday Mommy, Love, Kulture," the sign reads.

"Thank you sir," Cardi cheekily captioned the post. "I love it."

While the "Bodak Yellow" star did not specify who bought the billboard for her, fans in the comments believe that the gift came from Offset.

Cardi filed for divorce from Offset on in September after a three year marriage, according to the Fulton County Magistrate in Georgia. Their hearing is scheduled for Nov. 4 at 10 a.m.

If the speculation is true, and Offset was the "sir" behind the billboard, this wouldn't be the first time the Migos rapper did something grand to win back Cardi.

After the duo split in 2018, he crashed her headlining set at Rolling Loud in Los Angeles. Offset showed up with a lavish floral arrangement that read "TAKE ME BACK, CARDI," a gesture that didn't go over so well.

He and his flowers were removed from the stage.
