Piers Morgan says 'there's three people in marriage' to Celia Walden

Piers Morgan joked there are "three people" in his marriage to wife Celia Walden as the pair headed on a glitzy date night to a London restaurant. The former TalkTV presenter, 60, headed to Carbone in Mayfair with Celia, 49, and soon bumped into Arsenal manager Mikel Arteta - leading to a cosy snap with all three of them.

Piers joked on Instagram: "'There are three of us in this marriage, so it's a bit crowded...' Great to finally meet Arsenal manager Mikel Arteta last night, as we dined in the same restaurant. I told him he makes me happier than any other human being at the moment, that we've at last got a squad which will win the Premier League (we're top) and that I love all his new signings, especially our new striker Viktor Gyokeres.

"I may even have told Mikel that I love him on a personal level too, at which point Celia apologised to him and asked if he'd like her to call security (he laughed but declined the offer). Despite my fan-girling, he couldn't have been nicer or more friendly.

"Arsenal are very lucky to have such a classy guy at the helm, and I really do believe, as I told him, that this is the year the pain and torment ends, and we win the League again after 21 long agonising years. Let's do this Mikel!!"

Celia shared the snap to her own Instagram story, joking: "Three of us in this marriage. And I'll be the first to go."

Mikel wasn't the only A-lister Piers stumbled upon at Carbone, also posing for a snap with Dame Joan Collins as he gushed: "Dame Joan and a tray of gigantic cakes - does dinner get any better?

"I love Carbone in NYC, and heard the new London offshoot was just as good... so I took some friends to see if it lived up to the hype. There were A-listers everywhere, including the Clooneys, Princess Eugenie and Mikel Arteta."
