Blake Lively says the most important thing she looks for in a man is a good sense of humour.

The 'Gossip Girl' star is reportedly dating Hollywood heartthrob Leonardo Dicaprio and she has revealed she isn't just interested in physical attractiveness in guys.

She said: "I like someone who makes me laugh. I enjoy someone that's really fun."

The 23-year-old actress also likes men who share the same interests as her and admits she is a homebody as opposed to a part girl.

She added to the British edition of OK! magazine: "I'm very domestic. I love art, painting, interior decorating, baking. There are so many things I want to do in my life. I'd love to open restaurants and have an interior decorating business."

Blake is also very passionate about her charity work and believes she has a responsibility to use her fame in a positive way.

She explained: "I'm becoming very involved in charity work. I think it's important that we help our environment now for our children. Being in the spotlight, I have a voice. It's irresponsible not to use it in a good way."

In the past few weeks, Blake and Leonardo have been on a series of luxurious dates around Europe.

The pair were first spotted together on a yacht in Cannes, France, and also went to Venice last week, where they were seen in a water taxi on a canal.

Leonardo also treated Blake to a helicopter ride to Saint-Paul de Vence, France, for a $500 lunch at La Colombe d'Or Restaurant, a stay at the $5,000-a-night suite at Hotel de Paris and a trip on a $52 million yacht.
