Hugh Hefner's youngest son Cooper and his wife Scarlett Byrne are celebrating the arrival of twin girls.
Harry Potter actress Scarlett announced the news on her Instagram page on Tuesday.
Mum Scarlett penned: "'My heart grew twice as much this weekend as Cooper and I welcomed our daughters, Marigold Adele Hefner and Blossom Pearl Hefner into the world.
"Our home is full of love with our three daughters and we couldn’t be happier."
The couple, who tied the knot in 2019, are also parents to daughter Betsy Rose, who is now 15 months.
Their first daughter Betsy was named after Cooper's late grandmother Betsy Aldridge-Conrad, who passed away in July 2020.
At the time they shared a statement: "We are overwhelmed with joy to share that our daughter, Betsy Rose Hefner, has arrived.
"We look forward to being home and spending time together as a family in the days and weeks ahead."
They announced that they were adding to their family in November last year.
"Scarlett and I will be welcoming two new members of the family this spring. We couldn't be happier as we wait on the arrival of our twins,' captioned Cooper, before wishing 'A very Happy Thanksgiving to all!"
He shared, "My grandmother meant the world to both Scarlett and I."
Scarlett found fame in her teen years playing Slytherin student Pansy Parkinson in the Harry Potter film franchise.
She began dating Cooper after he contacted her on Facebook, five years after he attended the same US university as her former co-star Emma Watson.
Cooper went on to follow in his dad's footsteps and joined the family business at the age of 21 and later became Playboy Enterprises' chief of global partnerships and the chief creative officer.
When Hugh died at the notorious Playboy Mansion at the age of the age of 91 in September 2017, he made sure all of his children were taken care for.
The mogul left his four children from his first two marriages a huge sum of money each. He also left behind a Hollywood Hills mansion to his third wife Crystal Hefner to make sure she did not miss out, which she sold for $5million two years later.
Since his death, Cooper's late father has come under fire with a number of ex Playboy Bunnies speaking about torrid times with Hef.
Blonde twins Karissa and Kristina Shannon moved in with Hefner and his girlfriends and were given $1,000 a week to star on the hit reality show Girls Next Door, which documented the lives of the women living in the $100 million mansion.
Kristina said they were regularly given drugs as part of Hefner’s bizarre bedtime routine, before they engaged in group sex with the pensioner and a gaggle of other women.
Karissa said they were told the drugs - including weed and quaaludes - would help them feel more comfortable.

“He pulled out silk pyjamas from Italy and we put them on. He pulled out this big pill like the type a horse would take. It was quaalude, which we found out he used all the time.”
“He told us the drugs would help with our anxiety. We smoked some pot.
"We felt frozen at first but after a while the pill made us loose and fuzzy,” Karissa told the Mirror.
