Calum Best

Remember just a couple months ago when Lindsay Lohan and her new British BF, Calum Best, were making headlines? Well, we don't think it surprised anyone that things got rocky! For one thing, Calum bragged from the start that he'd hooked up with more than 1,000 women -- including Lindsay's frenemies, Paris Hilton and Kim Stewart (whom Calum was just spotted with last week!).

After Linds took him to the Bahamas (where he reportedly made out with a model behind her back) and showered him with gifts, Calum suddenly flaked out. When asked what he thought when his ex wound up in rehab, he said, "Who cares?" But in spite of everything, it was recently reported that Calum approached Lindsay about launching a new perfume together. Huh?
