The big jump: Ex-Olympic diving champ Louganis engaged, plans to marry in fall

NEW YORK, N.Y. - Former Olympic diving champion Greg Louganis plans to get married this year.

People magazine says the 53-year-old Louganis will marry paralegal Johnny Chaillot.

The four-time gold medallist is the only man to win consecutive Olympic titles in springboard and platform diving — in 1984 at Los Angeles and 1988 at Seoul.

After his diving career ended, Louganis revealed he was gay in 1994 and announced he was HIV-positive a year later.

Louganis is helping Olympic hopefuls as an athlete mentor for USA Diving. He's also been featured as a coach on ABC's reality diving competition "Splash."
