Hayden Panettiere has sparked rumours she is dating 'Entourage' star Kevin Connolly.

The 20-year-old actress - who has previously dated her 'Heroes' co-star Milo Ventimiglia and British TV presenter Steve Jones - attracted attention on Sunday evening (20.09.09) after spending the whole of the HBO Emmy Awards party holding hands and enjoying an intimate conversation with the 35-year-old actor.

A source is quoted by gossip blogger Perez Hilton as saying: "They were there to hang out together and stayed for hours until well after midnight. Kevin only left Hayden's side towards the end of the night when he wanted to chat with someone at another table."

News of Hayden's new romance will come as a big shock to millionaire Harry Morton, who Hayden was seen holding hands with just three weeks ago.

A source said: "He still thought he was dating her last week and told friends all about her. Harry was bragging about getting her to do anything he wants."

Hayden has previously admitted she doesn't find men her own age attractive.

She said: "I don't date boys my own age. I'm looking for the right guy, I always said I want four kids - I love kids. I would love to be a mother and to have a family."
