"Kissing your kids on the mouth is weird and dangerous these times..." wrote one follower.

Emma shared the sweet clip on Instagram.

Bruce and Demi have remained very close friends since their divorce in 2000.

In fact, the pair spent lockdown together with their daughters last year.

Emma eventually joined the clan for the rest of lockdown and there's certainly no bad blood between her and Demi - far from it.

When Bruce and Emma renewed their wedding vows in March 2019, it was Demi who was top of the invite list, with Emma admitting there was no way they would 'do it without' her there.

"She welcomed me into her family like I welcomed her into ours," she told Us Weekly.

"I have so much respect for how Bruce and Demi worked through their divorce to be able to put their children first. I learned so much from that and grew so much from watching that. It was important for her to be there."
