Oops she did it again...
Britney Spears has walked down the aisle for the third time. But this time the pop star is not tying the knot.
The 29-year-old singer played bridesmaid for her gay assistant and friend, Brett Miller in Miami, yesterday.
All smiles: Britney looked right at home in the Miami church
Flying into Miami on Thursday, the singer and her boyfriend Jason Trawick enjoyed a romantic weekend.
The pair stayed at the Newport Beachside Hotel, alongside several other friends who were part of the wedding party.
Enjoying an ocean-front room for two, the couple decided to spend some time on their own after arriving late on Thursday night.
'During Thursday night's rehearsal dinner, Britney ditched the reception and ordered room service for herself, Jason and her bodyguard,' a source told People magazine.
The wedding setting: the ceremony took place at the St. Bernard de Clairvaux Episcopal Church and The Ancient Spanish Monastry
The pair chose some comfort food from the hotel's menu.
'They had spaghetti bolognese, turkey burgers, chicken noodle soup, a fruit plate and one turkey sandwich,' said the insider.
Seemingly enjoying the hotel surrounds, they then surprisingly left the following day.
Privacy issues forced the couple to move to another hotel, with Britney complaining that the 'pool wasn't private' enough.
But what an upgrade they got...
They settled on a Frank Sinatra Suite at the Fontainebleau in Miami, where the $35 million penthouse rents for $15,000 a night.
Romantic: The church has a beautiful courtyard where guests can gather
With four bedrooms, a kitchen, whirlpool, piano and a large balcony overlooking the ocean, Britney and Jason had all the amenities at hand.
On Friday, they enjoyed a spot of shopping before attending another wedding party.
Keeping with the Sinatra theme, the pair waltzed to the crooner's tunes.
'At one point, during the early evening Jason took Britney's hand and twirled her to a cool Frank Sinatra sound,' the source says. 'It was cute and romantic.'
The dancing didn't stop there as the couple headed for the Fontainebleau club LIV.

'Britney and Jason were dancing and laughing and having a great time at LIV,' another source told PEOPLE. 'He was very sweet and affectionate with her. And she got very excited when her favorite songs came on.'
Britney's friend's wedding took place at Miami's Spanish Monastery.
