Simon, 45, looked dapper in a grey roll neck jumper as he held his adorable 10 month old daughter Cyan on the red carpet for the screening of Disney’s Turning Red.
He was joined by his wife Ayshen Kemal, who looked stunning in a monochrome suit.
And little Cyan already appears to be quite the fashionista, sporting a leather dress and a furry cream coat.

Antony and Rosanna have been in a relationship since July 2012.

Cyan was welcomed early by C-section after the couple previously experienced two heartbreaking miscarriages.

The father and son duo matched in their khaki jackets and blue jeans with brown boots for the outing.
Nathan, who won Love Island with his wife Cara De La Hoyde back in 2016, looked like a proud parent as he posed with his son and a placed an arm on his shoulder.

Nathan and Cara, who married in June 2019, are also parents to daughter Delilah, who was born in July 2020.
