It's heartbreak for female fans of the Backstreet Boys -- two of the hunky guys in the red-hot group are getting married!

Tearful teenage girls everywhere are calling the sexy blond fiancees of handsome Brian Littrell and Kevin Richardson "the luckiest women on earth."

These will be the first marriages among the five members of the super group, whose current album, Millennium, has sold more than 11 million copies in the U.S.

And it's left some of their young fans devastated. "I like Nick," says 9-year-old Hillary Sparling of Poughkeepsie, N.Y., "so I'm not so upset. But there's lots of girls who thought they had a chance to be Brian or Kevin's girlfriends who are going to be disappointed."

Kevin's soon-to-be Backstreet Bride is beautiful dancer Kristin Willits, who has kicked up her heels with the world-famous Rockettes and performed with Cher.

Brian's leading lady, Leighanne Wallace, is a buxom blond actress whose idol is Marilyn Monroe.

STAR has learned that Kevin, 28, proposed to Kansas-born Kristin, 29, on Valentine's Day.

Brian, 25, and Leighanne, 30, secretly got engaged too - and insiders reveal they've set a tentative wedding date of Sept. 2.

Leggy Kristin met Kevin before he rocketed to pop super stardom. The couple, who have been dating on and off for seven years, first laid eyes on each other at Disney World in Orlando, where he was playing a Teenage Mutant Ninja Turtle and she was dancing. "We've been through a lot together," Kevin says.

A year after they met, Kristin kick-started her career when she auditioned and won a place in line with the world-famous Radio City Music Hall Rockettes in New York City.

"I got to New York and heard the Rockettes were holding auditions and I thought, 'Why not give it a try?' And I got it on my first audition," she says proudly.

She also has performed as a backup dancer on tour with Cher.

And most recently she's appeared in Jim Carrey's movie Man On The Moon, where she played the part of a dancer for comic Andy Kaufman's alter ego, Tony Clifton.

Brian popped the question to Leighanne in front of her family on Christmas Eve at the suburban Atlanta home where she and her two sisters were raised - but kept the news of their engagement secret until now.

After dating since 1997, Brian finally decided Leighanne was the one for him and took the plunge. "There's a right time for everything, I guess," he says. "It's kind of like the jump-start on getting on with life, so I'm looking forward to it."

The wedding, which will take place in the Atlanta area, is set for Sept. 2. Fellow Backstreeters Kevin, Nick Carter, A.J. McLean, and Howie Dorough are expected to be Brian's ushers on the big day.

Brian and Leighanne, like a couple looking forward to parenthood, have gotten a dog they've named Tyk.

Leighanne - who is sporting a four-carat, fancy yellow diamond with sapphires on the side - is a blue-eyed beauty who has appeared on TV's Silk Stalkings and done a Mercedes Benz commercial with Jerry Seinfeld. She's been described as "the girl who turns heads" in the movie Wild America, which stars Johnathan Taylor Thomas.

She's also appeared in two Backstreet Boys videos, As Long As You Love Me and I'll Never Break Your Heart.

When Brian went underwent surgery two years ago to repair a hole in his heart - a condition he'd had since birth - Leighanne never left his side.

"I didn't leave him until I knew he was in perfect health," she says.

"It was one of the most scariest times of my life."

In addition to Nick, who at 19 is the youngest band member, the other unattached Backstreet Boys are Howie, 27, and A.J., 21.
