Heidi and new boyfriend Martin.

When did Heidi Klum and new boyfriend Martin Kristen start dating and then sleeping together?

Heidi and soon-to-be ex-husband Seal are the subject of a bit of celebrity scrutiny, specifically the issue seems to be Heidi's bodyguard Martin's sleeping arrangements as Seal has accused his wife Heidi of diddling the help.

When did Heidi and the bodyguard start their love affair?

Seal told TMZ in a recorded interview:

"Look boys, that's what happens when two people separate. They move on and that generally means [they have] other people in their lives."

"I necessarily don't expect to Heidi to all of a sudden become a nun, but as always, my main priority is the emotional well being of our children."

"To be quite honest, if there is going to be somebody else in their lives, I'd much rather it was a familiar face. I guess the only thing I would have preferred is that. . . I guess I didn't expect any better from him, I would have preferred Heidi show a little bit more class and at least wait until we separated first before deciding to fornicate with the help, as it were," Seal told TMZ.

"But I guess you now all have the answer that you've been looking for for the past seven months."

Ouch!

Is Martin now Heidi's boyfriend?

Reports (and Seal) have made the claims, and even though one pal admitted the supermodel has got "very close" to her bodyguard since separating from the singer - whose hard partying was rumored to have contributed to the marriage breakdown - the pal claims their relationship is currently "undefined".

The chatty source added: "It’s sad but not surprising that he would resort to making excuses for their divorce when the real reason is looking him in the mirror."
