WSVN -- P. Diddy may seem like the king of cool, but this music mogul is beginning to lose his cool, as things with his divorce get even nastier.

The star was in London launching his new perfume line when a pushy paparazzi asked Diddy if he was having a fling with British beauty Sienna Miller. Diddy reportedly had to be held back from knocking the guy out.

Then it was on to St.Tropez where according to one insider, Diddy has been demoted to a B-lister. Well, at least its not the D-list.

Rocker Lenny Kravitz is getting ready to jam to a new tune, this time at the altar. According to friends of the bride, Kravitz met grad student Katia Kovaleva at a concert after-party while on tour in Russia, and the pair have been quietly engaged for over a year.

The wedding is said to take place in the Bahamas during the holidays.

Now for some more star sightings around town.

Janet Jackson doesn't miss those calories much. The star was seen with pals at the Forge drinking water and dining on Chilean sea bass.
