Britney says this marriage is for the right reason

This time, she’s marrying for love, Britney Spears says of her recent engagement to dancer Kevin Federline.

“Marrying Kevin was the last thing I was thinking about doing,” Spears tells People magazine in its July 12 issue. “But then I said, ‘You know what? This is my life and I don’t care what people think. I’m going to get married. I’m in love with him.’ ”

Spears, 22, and Federline, 26, began dating a few months ago, after her Las Vegas wedding to childhood friend Jason Allen Alexander in January. That marriage was annulled 55 hours later. “That thing was a total ugh,” she says. “I was not in love at all.”

Federline, who performed as a backup dancer for Justin Timberlake, Spears’ former boyfriend, previously was involved with Shar Jackson, star of TV’s “Moesha.” They have a 2-year-old daughter and are expecting another baby.
