They’ve been linked since August when they were spotted on a theatre date in London’s West End.

Lily and David had been seen together a number of times over the last few weeks, including a date night at the Hughie Fury vs Alexander Povetkin boxing match at London’s O2.

The Smile hitmaker now seems to have made things social media official, signalling they are exclusively dating.

She had supported David during his SNL hosting debut on Saturday night and was even spotted leaving the show alongside the actor’s family. 

The London-based star also hinted she was going to stay with David in America until the Brexit deadline of October 31 when the UK is due to leave the European Union. 

Sharing a number of selfies of herself, the singer wrote: ‘Leaving UK till after Brexit. Good Luck Kids. Also what’s the most annoying engagement baiting question caption you’ve read ? LMK in the comments’.

After lunch at Cafe Gitane, Lily and David – best known for playing Jim Hopper in the Netflix sci-fi series Stranger Things – ambled along side-by-side. 

The pair stopped to share a kiss on the lips, confirming fan speculation they are more than friends. 

Lily separated from husband Sam Cooper in 2015 after about four years marriage, finalising their divorce in 2018. 

They share joint custody of their two daughters Ethel, seven, and Marnie, six, and remain ‘really friendly’ to this day.

During an interview on Loose Women back in 2018, she said: ‘[Our custody agreement] wasn’t really something we discussed, we’re both really friendly, our kids go to school equidistant between our houses, so it works.’

Following their separation, the songstress was in a relationship with grime DJ MC Meridian Dan, real name Daniel Lawrence London.  

The pair first started dating three years ago, but Lily told How To Fail podcast host Elizabeth Day they had split in December 2018.

She said at the time: ‘I’m single, for the first time since I was about 15. I’ve just come back from a tour in America, which is where I was when things went wrong with Sam, and the same thing happened in my current relationship.  

‘I mean, I didn’t take lots of drugs and have lots of sex with other people. I just became very lost.’

David is believed to have split from Fantastic Beasts star Alison Sudol earlier this year after a year and a half of dating.

The pair were last seen in public at the Hellboy screening in NYC in April, but have remained quiet about their break-up.

The American actor previously discussed what he looks for in a partner in an interview with Women’s Health.

He said: ‘I’m easily swept away, but I’m trying not to be as much. I’m better at the fantasy of relationships than I am at the daily real life, but I’m trying to steer myself into a realist. 

‘What I find most exciting now is sharp, intelligent, insightful women. People who are deep thinking, who have sort of a weird way of looking at the universe are wildly attractive to me. 

‘So if I can find one of those gals who can stand me, then maybe I might have something thing.’
