Heidi Klum, 53, heats up the red carpet with her VERY handsy husband Tom Kaulitz, 37, before hanging with the Hilton sisters during PFW

Heidi Klum and her husband Tom Kaulitz were showing major red carpet love at a high-profile launch party during Paris Fashion Week on Friday.

The supermodel's husband couldn't seem to keep his hands off her as they posed up a storm at the Paris With Love bash, which was hosted by Maison Karl Lagerfeld in celebration of their Fall/Winter campaign featuring Paris Hilton.

Klum, 53, was a combination of sultry and sassy in a strapless black mini-dress with sweetheart neckline, while the Tokio Hotel guitarist and songwriter, 37, wore a sleek, dark suit.

It's been seven years since the couple wed in a secret civil ceremony, followed by a second wedding aboard a luxury yacht six months later, but clearly they are still in the honeymoon phase.

Klum, who celebrated Oktoberfest in Munich with her husband last month, managed to peel her way out of Kaulitz’s arms, long enough to make a beeline for Hilton, 45, and her sister Nicky, 42, for social time and photo ops.

They’ve crossed paths over the past two decades at the same exclusive parties and international runway shows, and seemed to have a blast reconnecting here in the City of Lights.

Klum and Hilton, who both made separate appearances in the 2001 comedy Zoolander starring Ben Stiller, were seen chatting among the bustling activity at another point.

Hilton wore a two-piece number with shimmering long-sleeved top and flowing skirt matched with stiletto pumps.

Her long platinum hair was arranged half up, half down to perfectly frame her face.

Nicky, on the other hand, opted for a slinky black number with sheer black panels on the sides and crisscrossing details in front.

Klum appeared to be on a continuous high after walking in the L'Oreal Paris 'Le Defile' show on Monday and the Ottolinger Spring/Summer 2027 show on Friday.

On September 20, the Project Runway host made an impression during the Oktoberfest celebrations at the Braurosl beer tent in Munich.

A few days earlier, on September 17, she hosted her second annual HeidiFest at the Hofbrauhaus in Munich.

And there she was joined by her husband, her son Henry and eldest daughter Leni along with her mother Erna Klum and Fritz, the family’s dog.

Klum is known for her generosity toward her family.

Just last month, the fashionista splurged on a special 21st birthday gift for her son Henry.

Klum and Kaulitz pulled out all the stops, spending more than six figures on a red Ferrari F430 to celebrate Henry's special day on September 12.

In a video shared on Instagram, Henry appeared stunned as he walked out of the family home with his stepdad following behind and saw his flashy new sports car waiting for him in the driveway.

As he caught a glimpse of the Ferrari, Henry exclaimed: 'Oh my God! I don't even know what to say.'

'I can't believe it is that time. You've been waiting for so many years,' Klum told him.

As Henry and Kaulitz marveled at the vehicle, the latter explained that he bought it at an auto show 'last year' and hid the Ferrari in the garage 'the whole time.'

'This thing is beautiful. Holy s***! Oh my f****** God, this... is insane. Holy s***, this thing is crazy,' Henry went on.

Klum noted that Kaulitz 'kept his promise' after losing a video game bet to a then-14-year-old Henry, which meant he had to buy his stepson a Ferrari when he turned 21.

'Literally, it's what? Seven years ago when you guys said that?' Klum said.

Klum also shared the clip in which Henry and Kaulitz made their Mario Kart bet.

Henry was seen saying: 'It's happening on Christmas, and if I lose Mario Kart, then I can't play video games for three months, and I have to give him a painting of me driving.

'But if I win, then Tom has to give me a Ferrari when I'm 21.'

In addition to Henry, Klum has son, Johan, 19, and daughter, Lou, with her 63-year-old ex-husband, singer Seal. 

Seal also legally adopted Klum's daughter Leni, 22, who she has with her former partner, businessman Flavio Briatore, 76.
