Bethenny Frankel was spotted with new beau Michael "Mac" Cerussi III in Miami Wednesday, sipping cocktails and ringing in the new year at the Mondrian hotel in South Beach.

The sexy 43-year-old TV hostess showed plenty of skin in a tiny two-piece -- so tiny that the top looked a bit too tight to contain everything.

"Finally a nice beach day in Miami," she Tweeted. "Jumping into the ocean to plunge info the new year."

Frankel and financier Cerussi, 34, spent New Year's Eve together, and sources tell In Touch Weekly magazine that they were spotted getting very close.

"Bethenny looked very happy to be kissing Mac in public -- it's like she knew she was ready to go public with him," the source said. "When I saw them at the Mondrian, she was kissing him in front of her friends and posing for photos together."

The reality star-turned-talk show host recently told People magazine that she wasn't ready to date anyone yet because of her messy divorce from husband Jason Hoppy. The couple split after two years of marriage and battled in court for months over their daughter Bryn, 3.

Seems like she's found Mr. Right, or at least, Mr. Right Now -- Bethenny has been married twice and engaged four times. Her first marriage lasted a year, and her second lasted just two.

Can you say, 'commitment issues'?

“I don’t believe in The One or only one soulmate,” she told People magazine back in September. “Maybe there is The One, but that doesn’t mean it’s the person you live with your entire life. Your soulmate may or may not be the person you married. It doesn’t happen often.”
