He is one of Britain’s most eligible bachelors – but Poldark actor Aidan Turner may finally be off the market.

Our pictures show the TV hunk leaning in to kiss a mystery brunette after lunch in the West End of London.

The pair could not stop laughing as they walked through Soho before Aidan puckered up to his new leading lady.

An onlooker said: “He was really into her. He didn’t care who saw them.

“They had a natural rapport and were having a great time.”

Aidan split with actress Sarah Greene, 32, in November after nearly five years.

Then in April he was spotted with ex Lenora Crichlow , 31, in Los Angeles, sparking rumours they could be back together.

The Irish star is wary of speak­­ing about relationships, previously stating: “I like to keep my private life private for my own head.”

The 33-year-old is one of the hottest stars on TV after stripping off in the first series of the drama and rescuing earthy Demelza played by Eleanor Tomlinson.
