Britney Spears plays bridesmaid for a friend's wedding; Could she be next down the aisle?

Britney Spears was in the wedding spirit on Saturday (Jan. 29), as she was on hand for assistant/friend Brett Miller's Miami nuptials.

Spears walked down the aisle as a bridesmaid in a long, turquoise gown.

Boyfriend Jason Trawick was also on hand, reportedly being "very sweet and affectionate" with Brit Brit.

Despite her bridesmaid duties, People reports that Spears skipped out on the traditional rehearsal dinner Thursday night. Instead, ordering room service for herself, Trawick and a bodyguard in the hotel room.

The pop-tart was on hand Friday for another wedding party, as she and Trawick were spotted twirling to Frank Sinatra on the dance floor. Says a source, "It was cute and romantic."

Could more wedding bells be in Spears' future?

The couple has been involved since 2009, and after taking a break from their business partnership to focus on their romantic relationship, the two recently announced that they are working together once again.

After two failed marriages on Spears' end, we hope the third time will be a charm!
