Bethenny Frankel has laughed off rumours she's dating Eric Stonestreet.

The 'Real Housewives of New York City' star, who split from estranged husband Jason Hoppy in 2012 after two years of marriage, has formed a close friendship with the 'Modern Family' actor in recent months, but has brushed off speculation they're a couple.

The 44-year-old entrepreneur, who has five-year-old daughter Bryn, addressed the romance rumours on Twitter, writing: ''Wow #somanyboyfriendssolittletime How did I manage to be at a @Dodgers game & be in the Hamptons at the same time?!!! @ericstonestreet''

A source close to the duo confirmed they have recently been ''having fun'' together.

The insider told PEOPLE.com: ''They are talking and they have been friends since they met at CAA upfront party in April. He is in L.A. and she is in the Hamptons. They are hanging out. They are having fun and she likes his company.''

But a second source told UsMagazine.com: ''This is so dumb. They are friends and have a lot of mutual friends in the same circle. They definitely are fond of each other and like each other but it's not serious.''

Eric, 43, was previously linked to Oscar-winning actress Charlize Theron following his split from his Broadway girlfriend Katherine Tokarz in September 2012 after three years of dating.
