Britney Spears walked down the aisle! But it wasn’t for herself — she was a bridesmaid in a wedding for her friend, Brett Miller.

On Saturday, the pop princess wore a blue dress after flying in on Thursday to make it for the festivities.

Britney and company holed up in a oceanfront room at the Newport Beachside Hotel where members of the wedding party were staying. A spy on the scene said that Britney didn’t make it for the reception. The source said, “During Thursday night’s rehearsal dinner, Britney ditched the reception and ordered room service for herself, Jason and her bodyguard.”

The source revealed, “They had spaghetti bolognese, turkey burgers, chicken noodle soup, a fruit plate and one turkey sandwich.”

Britney left her friends and parents at the Sunny Isles hotel on Friday and opted to stay at the more private Frank Sinatra suite at the Fontainebleau Hotel in Miami, because the Newport’s pool wasn’t “private enough”.

That suite cost her a whopping $15,000 a night!

Afterward, Britney hit up another wedding party with Jason at the Newport Hotel. The source said, “At one point, during the early evening Jason took Britney’s hand and twirled her to a cool Frank Sinatra sound. It was cute and romantic.”

How cute! It’s good to see that there wasn’t any truth to the rumors that he was beating on her.
