Los Angeles, California - Britney Spears' sister and mom, Jamie Lynn and Lynne, have reacted to the star's impromptu wedding to Sam Asghari.

Though they weren't on the invite list – for obvious reasons pertaining to her conservatorship – it seems Britney's family is excited for her future as Mrs. Asghari.

Well, at least her mother and her sister are.

On Friday, Lynne surprisingly congratulated her daughter in the comments section of the pop singer's Instagram post.

"You look radiant and so happy! Your wedding is the 'Dream' wedding! And having it at your home makes it so sentimental and special!" Britney's mom wrote to her daughter.

"I am soooo happy for you! I love you!"

While the pop singer's mom outwardly showed her daughter and new son-in-law some love, her sister chose a more subtle route.

Jamie Lynn showed her support by liking the same photo dump of shots.

The newlywed hasn't addressed her family's absence from her ceremony to her one-time backup dancer. Yet, it didn't seem like she was bothered about them not being there.

On Thursday evening, Britney and Sam got hitched in front of 60 of their closest family and friends at the singer's home in Thousands Oaks.

Among those in attendance at the star-studded ceremony were Donatella Versace, Madonna, Paris Hilton, Selena Gomez, and Drew Barrymore.

One person who hasn't spoken on Britney's wedding is her father Jamie, who's been on the outs with the Circus singer following the termination of her conservatorship and his involvement.

At least the pop singer's family didn't try to foolishly crash her wedding, like her ex-husband Jason Alexander did.
