Sealed with a kiss! Exes Heidi Klum and Seal share a friendly smooch as they put on united front to take the kids for Christmas Eve dinner

They have remained amicable after splitting nearly four years ago. 

And on Christmas Eve, Heidi Klum and ex husband Seal decided to take their four children - sons Henry, 10 and Johan, nine and daughters Leni, 11, and Lou, six - out for a Christmas Eve family dinner at Matsuhisa in Beverly Hills.

With the exception of Seal, the family was dressed to the nines, with fashion icon Heidi leading the way.

Christmas surprise? Given her current muddled relationship status, it's hard not to read into Heidi Klum's interesting interaction with ex Seal on Thursday evening

The Project Runway star kept her ensemble quite demure, sporting a black knee length dress under an equally long black coat, and some pointed black ankle booties.

As it was quite chilly, the supermodel opted for some sheer tights and wrapped her shoulders in a regal black fur stole. 

Her famous shimmering blonde locks were pulled up an back into a tight bun, and she added a dash of color to the whole look with a small, fuzzy mulberry red purse.

In comparison, ex Seal showed up in a markedly casual getup for the family affair, donning some white trainers, athletic pants and a white sweater. He layered an olive, fur-collared parka on top.

Trying to say something? While the quick kiss in the parking lot appeared quite spontaneous, it also appeared to be more than a simple peck on the cheek

While the quick kiss in the parking lot appeared quite spontaneous, it also appeared to be more than a simple peck on the cheek.

There have been claims that Heidi Klum split from beau Vito Schnabel after he started spending time with Dakota Johnson.

The 42-year-old model has not been seen with the 29-year-old art dealer in a month. They started dating in spring 2014.

And on Thursday the German star added even more fuel to the rumours that she was now single when she posted a cartoon Christmas card that left out the handsome New York native.

'Merry Christmas From my family to yours,' the blonde captioned the picture.

In it, the leggy Project Runway host wears a cap that says Mama as she huddles with her brood that includes daughters Leni and Lou as well as sons Henry and Johan.

Even her two dogs made the scene, which was by a Christmas tree.

Are they really over? Klum seemed so happy with Schnabel; here they are seen in September

On December 9 he was seen at the White Horse Tavern in New York's West Village with Johnson, the daughter of Melanie Griffith and Don Johnson.

The actress made a splash earlier this year as the lead of the hit film Fifty Shades Of Grey. 

Vito looked happy as he sat next to the dark-haired beauty on a bar stool.

Though there was no PDA involved, his legs seemed to be touching her. Also with them was a blonde friend.

Star magazine reported this week that Schnabel has been 'cheating' on the mannequin with the Hollywood royal. An eyewitness claimed that at one point Vito held her hand and pushed back her hair behind her ear.

Reps for both Heidi and Dakota did not return calls to DailyMail.com.

The art expert was in black with his long locks slicked back. Dakota was casual with her hair in a ponytail and a striped shirt on with black slacks.

There was no doubt that was Johnson he was with.

The beauty's neck tattoo - which spells out Amor in a foreign language - was on display thanks to her hair style. 

Reaching out: Heidi hared a video to Instagram on Wednesday where she was helping children in India

The last time Heidi was seen with Vito was on November 15 when she took him along with her parents and four children to lunch in Malibu.

There has been no announcement that Heidi and Vito have split. 

They started dating in the spring of 2014 and quickly were seen globe trotting together while sneaking in kisses.

A warm welcome: The 42-year-old supermodel went makeup free as she cradled babies and took in the local culture as a part of her mission with UNICEF

In Paris they were seen arm in arm. In Los Angeles, they held hands.

Before Vito, the blonde German goddess was married to singer Seal, with whom she had three children. Her first child was with businessman Flavio Briatore, 65.

Meanwhile, Dakota has not been seen with her beau Matthew Hitt since October.

Heidi has not been crying at home.

The catwalker appears to be in great spirits during the trip, which was taken earlier this year.

Klum wrote on her Instagram page: 'Humbled to be part of such an amazing organization.'

She added: 'I took an extraordinary trip to India, where I witnessed UNICEF’s lifesaving work – from treating underweight and premature babies to teaching school children about the importance of handwashing.

'Help support this amazing work through @UNICEFUSA.'
