The latest survey by Fox News putting him on 25 per cent support among Republican voters- that is more than double the support of his nearest rival in the poll, Ben Carson who had 12 per cent.
He has been accused of claiming Megyn Kelly gave him a hard time at the first Republican primary debate debate because she was in her menstrual cycle.
And the politician also came under fire for proudly owning up to calling Rosie O'Donnell a "fat pig" during the debate.
And now the reaction of Klum threatens to again put the spotlight on his controversial comments about women.
In the interview with the New York Times, Trump insisted he was not misogynist and said: "Sometimes I do go a little bit far."
Then he added: "Heidi Klum. Sadly, she's no longer a 10."
The supermodel responded by posting a mocking video on social media.
In the clip, the mother-of-four poses for a photographer in a fashion shoot, wearing a cropped white T-shirt with a "10" emblazoned on the front.
Suddenly a man approaches her from behind - wearing a crude Donald Trump mask with eyeholes cut out - and he rips the 10 from her chest... to reveal a 9.99 underneath.
Klum gasps in mock shock, surveys her new rating, shrugs and then continues smiling to the camera.
"#TrumpHasSpoken #sadly #9.99 #NoLongerA10 #IHadAGoodRun #donaldtrump #trumped #HeidiTrumpsTrump #BeautyIsInTheEyeOfTheBeheld," she captioned the video.
It's not the first time the 69-year-old father of five has commented on Klum.
In an interview with Howard Stern in 2005, just after she had given birth, Trump claimed: "I looked at her the other day, and it's off. There's no question."
On that same show, Trump was heard rating other women in the public eye, including the "very flat chested" Nicollette Sheridan; and Carmen Electra whose implants "look like two light bulbs".
As for actress Halle Berry he said: "From the midsection to the shoulders, she's a 10. The face is a solid 8. And the legs are maybe a little bit less than that."
Trump most recently came under fire for an exchange with Fox News journalist Megyn Kelly, after he appeared to suggest she was on her period during the GOP debate.
"You could see there was blood coming out of her eyes. Blood coming out of her wherever," he said.
Trump refused to apologise afterwards, and seems happy to drink up the attention that has him leading the Republican polls.
