Liz Hurley led the tributes to her lookalike son Damian as he rang in his 17th birthday.
The actress and model was joined by a whole host of a-list celebrities, including Elton John and Joan Collins, who also publicly wished Damian a happy day.
Sharing a picture of her long-haired son to Instagram - who fans often say looks just like his famous mum - Liz, 53, spoke of how proud she was of her boy.
"Happy 17th Birthday to my heavenly @damianhurley1 . No one could have brought me more joy. You have made me a very proud mama'.
Celebrity pals including Elton John, his husband David Furnish and Joan Collins then piped up on social media to send Damian best wishes.
Elton and David are godfathers to Damian - along with Liz's ex Hugh Grant.
The polite teenager then responded to their messages saying 'love you!! xxx"
Liz shared Damian with her ex Steve Bing, who initially denied paternity until a 2001 DNA test proved otherwise.

Liz and Damian share a very close bond and fans often comment on their likeness.
For her Instagram tribute to Damian's birthday, Liz shared several pictures of them together.
In one smiley snap, Damian was sporting a camo top that looked very similar to one his mum has sported in the past.
Liz also shared some throwback snaps of her boy when he was a baby.
The Royals actress previously caused a stir when she revealed Damian was often the photographer behind some her racy Instagram bikini snaps.
In her defence she said: "When we're on holiday together, sure he'll take some pictures. And you know, he's got a really good eye and he's studying photography."
The Royals actress, who refers to son Damian as her "soulmate", said that he also helps her out by lending her some of his comfy clothes.
"I tend to wear Damian's cast-offs," she told Extra back in October. "His 14-15-year-old trackie bottoms fit me perfectly."
