Sir Rod Stewart celebrated his son's birthday yesterday and fans cannot believe the 'handsome' resemblance between the pair.
Dad-ofeight Rod and the family celebrated his second youngest Alastair, who he had with wife Penny Lancaster, as he turned 16.
The 76-year-old posted a snap on his Instagram page of the pair enjoying a meal at Nobu in London.
The birthday boy, wearing a Palm Angels zipper, wrapped his arm around his father and smiled to the camera.
Rod opted for something a bit more formal, wearing a black suit jacket, a tartan tie with a Celtic pin attached.
He wrote: "Happy 16th birthday my boy @alastairwstewart, love ya, up the Hoops."
Taking to the comments, fans predicted Alastair would be a heart-breaker like his dad.
One wrote: "Happy birthday to that handsome son on of yours."
Another added: "He’ll be a ladies man like you Rodster !"
While one wrote: "A couple of handsome men!!"
Another added: "What a handsome young man."
While one said: "I can’t believe how the years fly by. Handsome young man, oh, and of course his Dad as well."
And one wrote: "Happy birthday to this handsome gentleman."
It comes after Rod posted a rare snap of himself with his two sons Alastair and Aiden at a charity ball following his performance on the Graham Norton Show.
The Baby Jane singer took Alastair and 10-year-old Aiden to a Football For Change charity event to help raise money for underprivileged kids.

Rod cuddled up to his two boys, wearing his signature leopard print blazer and matching shoes.
The 76-year-old posted the photo on to his Instagram account, along with a video of him on stage when he was asked to give the audience a tune.
Kind-hearted Rod said he was there to show his support as “life has been kind to me, I’ve made lots of money and you have to give a little back.”
He then proceeded to delight fans with an acapella rendition of hit song Have I told You Lately That I Love You.
