HEIDI KLUM gives new BF bone- crushing man-gina makeover!

 IF you’re going to date a supermodel, you’d better look the part – and the “Project Runway” beauty is sparing no expense to make sure her new beau is dressed to the nines!

The 39-year-old recently dropped a whopping $10,000 on clothes for her bodyguard-turned-boyfriend, Martin Kristen, during a Beverly Hills shopping spree at Barneys.

“She would have BOUGHT OUT the entire men’s department but he put up a fight,” a fellow shopper told The ENQUIRER of the Sept. 21 out­ing. “She actually only bought him a couple of new suits, some shirts and two pairs of shoes, but the bill turned out to be more than $10,000 because Heidi only gets the best of the best.”

According to the source, Martin was shocked when he saw the bill.

“He nearly had a heart attack,” said the source. “He’s got a lot of pride and he’s not into fashion, so it took a lot of convincing to get him to go shopping in the first place. He really doesn’t want Heidi to spend money on him. But Heidi finally dragged him to Barneys and basically pointed out everything she wanted him to wear.”

Martin was uncomfort­able with Heidi spending so much money on him, but she refused to let him return the clothing.

“Her image is everything, so having a fashionable boyfriend is very im­portant,” explained the source, “and now that Martin’s with her, he has to respect that.”

Mom-of-four Heidi recently admit­ted she was dating Martin, who has been a constant presence since she split from British singer Seal, 49, in January. “Heidi is crazy about him,” added another source. “He’s really helped her get through a very hard time in her life, and she’s having lots of fun spoiling him.”
