Supermodel Tyra Banks could be set to walk down a different kind of runway — as she looks to be sporting a ring on her wedding finger.

The 32-year-old was spotted on Oct. 15 enjoying a romantic day by the pool with a mystery hunk at the Setai Hotel, one of Miami Beach's most exclusive. She looked stunning in an orange bikini and a brown patterned sarong wrap — but it was the new man and the ring on her finger that set tongues wagging.

The talk-show host, who used to date basketball star Chris Webber and movie-maker John Singleton, made it clear she was more than just good friends with the hunk.

As they relaxed by the pool and went for a stroll by the beachfront, the two could be seen kissing, stroking each others' legs and holding hands.

An onlooker said: "They were definitely not just hanging out — they were completely into each other and looked very happy.

"They were very tender with each other and didn't seem to care who saw them — Tyra made no attempt to hide the ring on her wedding finger."

Banks, who hosts America's Next Top Model as well as her own daytime talk show, has said recently that she is ready to marry.

She said: "I'm not living in fear that I will never find love anymore. I want to get married. I want to have kids."
