Britney Spears is keeping it all in the family for her forthcoming "My Prerogative" video: Two of the closest men in her life are making cameos.

Spears' brother, Bryan, makes a brief appearance in the beginning of the video, while her fiancé, Kevin Federline, plays a crucial part at the end.

Spears' mother posted on the singer's Web site Monday, telling fans to keep an eye out for "that good-looking hunk of a son of mine," while also describing some of the shoot itself, and how the production managed to work around the singer's injury (see [article id="1488285"]"Britney Busts Knee, Complicating Video Shoot And Tour"[/article]).

"Since Britney's knee is unable to do choreography, the video is all about capturing gorgeous close-ups and very subtle movement," Lynne Spears wrote. "It has an element of old Hollywood glamour and mystery."

Part of that mystery, though, comes from the video's story line, which makes it appear that Britney has crashed a party -- literally -- and needs a new dress after hers is soaked from driving into the pool (see [article id="1490312"]"Britney Makes Party-Crashing Her Prerogative In Next Video"[/article]).

After going to a bedroom and putting on a new dress, she makes her way to the party outside, where people are gathered, looking like they are waiting for someone, something. Only then is it revealed that the dress the singer put on is a wedding dress, and the party she's crashed is her own wedding.

As she walks down the aisle, the groom is then revealed to be Federline, her real-life future husband (see [article id="1486880"]"It's True: Britney's Engaged"[/article]), according to a source close to Spears, and the video's statement is then made all the more clear, as she sings rebelliously, "It's my prerogative."

Spears' Greatest Hits: My Prerogative LP is due November 16.
