Sean Penn has no issues with admitting he is absolutely besotted with Charlie Theron, and the 54-year-old actor is so in love he recently admitted he would even consider walking down the aisle with the South African star.

However, even though Penn has been married twice before, he said to the March issue of Esquire UK that if they were to tie the knot, he wouldn't consider Theron to be his third wife.

"Yes, I'd get married again," he told the mag. "You say I've been married twice before but I've been married under circumstances where I was less informed than I am today, so I wouldn't even consider it a third marriage, I'd consider it a first marriage on its own terms if I got married again."

"I mean, I like the tradition," he continued. "A friend of mine wrote a line, 'Without tradition, new things die.' And I don't want new things to die."

Penn, who went public with his relationship with Theron over the Christmas holidays last year, was previously married to pop icon Madonna and American actress Robin Wright, who he shares two children with.

The Oscar-winning actor also revealed to the magazine that he was generally surprised about how much their relationship blossomed over a short period of time.

"Yeah, I'm surprised to be in love," he told Esquire U.K. "Lot of reasons. I'm self-proclaimed bad at mathematics but I can do two plus two: 53 years old plus finally beginning to figure out why you haven't been happy in a single relationship? It could seem too late. But to run into somebody now who you care about is a much more passionate, deeper, truer and - God! - a much happier feeling. It's a lot more romantic and a lot more fulfilling to be in a relationship and to think you're a good person within it."
