Music producer supremo Mark Ronson has married partner Grace Gummer – the daughter of Hollywood actress Meryl Streep.

Ronson, who was celebrating his 46th birthday on Saturday, announced the news of his nuptials in an Instagram post to his 900,000 followers, sharing a black and white snap of their wedding day.

He wrote in the caption: “To my truest love…out of nowhere, you made 45 hands down the greatest year of my life. And i’m sure it took me 45 years to become the man worthy of your love.

“I hope I spend every one of these birthdays by your side til [sic] my last day. And beyond. Forever and ever yours (and yes, we got married).”

There had been rumours that the pair were engaged earlier in the year, and made their first appearance together in July at a Gucci event in the Hamptons, New York.

Gummer, 35, followed in her mother’s footsteps and went into acting, and has starring roles in Mr Robot, The Newsroom and American Horror Story.

She is currently appearing in Peacock’s Dr. Death, alongside Christian Slater.

Gummer was previously married to musician Tay Strathairn.

Ronson is the man behind several mega-hits, including Uptown Funk with Bruno Mars, Valerie with Amy Winehouse and Oh My God with Lily Allen.
