Heidi Klum hurt by separation from Seal

Heidi Klum has been tight-lipped since her January split from Seal, but she opens up a bit in the cover story of the April issue of Elle.

The two, who married in 2007 and have four children, announced their split just as Seal, 49, was setting out on a media tour to promote his latest album. The musician has spoken openly about his feelings, something the supermodel, 38, says she sees no need to do.

"I don't want to talk positively or negatively about the ups and downs that we had. Every couple goes through things," Klum said while acknowledging that the separation has hurt her. "I'm not a robot. I'm not made out of stone.

"With my life, my family, my business -- I want to go forward," she added.

Like father, like son

It's not exactly what comes to mind when one hears the phrase "father-son time."

Rapper Coolio, 48, is in Las Vegas' Clark County Detention Center, the same facility that's holding his oldest son, Grtis, 22. Coolio was arrested Friday after a routine traffic stop, according to www.tmz.com. Evidently there were two bench warrants out for the rapper's arrest stemming from multiple traffic violations. His son has been at the Clark County jail since November.

TMZ learned Friday that Grtis is being held without bail on multiple charges, including robbery with a deadly weapon, first-degree kidnapping and grand larceny. He and a prostitute named Shantrice Wilkerson are accused of entering an apartment with a gun, forcing one of the tenants into a bathroom at gunpoint and stealing whatever they could find.
