Britney Spears and Sam Asghari marry in an intimate ceremony on Thursday

Britney Spears is ready to walk down the aisle and marry her fiancé Sam Asghari in an intimate ceremony.

Sources close to the singer told TMZ that the couple were getting married Thursday in front of a small, very exclusive guest list of around 100 people. We are told that Britney’s brother, bryanshould be present — but his mother, father and sister, Jamie Lynnwon’t be there.

Our sources say it has yet to be decided who will give Britney to the altar, as the final details are still being worked out.

BS posted a video of herself with Sam on Wednesday and her nails certainly looked wedding ready as she and Sam cruised around town sipping champagne in a Rolls-Royce.

The wedding has been in the works for months…remember, Sam ask the question in September, shortly after being spotted buy rings.

Britney and Sam partied during their engagement… jet set in Cabo, Cancun, Las Vegas and Hawaii… where they were jet skireservation lavish suites and dine at the trendiest restaurants.

It’s unclear what Britney will wear to the big event, but she did document a visit from Donatella Versace in March – so that could have been a big clue as to who designed her dress.

Britney clarified she wanted to get married, buy a house, and have kids after her conservatorship ended…so she’s about to tick off a major part of that list.

While Britney and Sam announced she was pregnant in April, she says she tragically had a miscarriage …even though BS says the couple are still trying for a baby.

The couple met in 2016 while filming Britney’s music video for “Slumber Party” and have fallen in love ever since.

This will be the third time Britney has walked down the aisle – she was previously married to Jason Alexander and Kevin Federline — and the first for Sam.
