Calum Best can’t keep his mouth shut – which is not good for Lindsay Lohan. Lohan, who always plays coy about her romantic relationships, may soon find that Best is more interested in gaining fame than in their fling.

The well-known lothario recently spoke to OK! magazine about dating Lindsay. He said, "It's early days but it's going real great. She's a fantastic girl, so watch this space I guess.�?

Though rumors claim that Calum was flirting with girls behind Lindsay’s back, he says that he’s looking for a serious relationship. He told OK!, "I've been young, free and single and sowing my oats since I was 15 years old, but I've now reached a point where if I had a girlfriend I could commit to her and put in 110 per cent."

Maybe Lindsay is the one to tame Calum. The 26-year-old is now back in London, but he is still talking about the time he spent with 20-year-old Lohan. He says, "We met when she was in London last year and kept in touch. Then she invited me to New York last week for a premiere, so I went along. After that, we headed to Paradise Island in the Bahamas to chill out away from it all and it's going well.�?
