Rod Stewart's son celebrated his 19th birthday with a group of his pals in Glasgow after whizzing in on a private jet.

The 79-year-old's son, Alastair Stewart, flew to the city along with his friends and dad recently to celebrate the milestone.

The teenager took to social media earlier this week to share pictures from his trip.

Alastair could be seen towering over the Maggie May singer wearing a posh suit and furry coat.

Once the team stepped off the jet, they headed to Anchor Line on St Vincent Place.

The gang then appeared to head to Celtic Park, where they all donned Hoops ties, to watch the Glasgow side, and Rod's beloved team, take on Club Brugge in the Champions League.

The match finished 1 - 1. Following watching the two football teams battle it out, the lads then headed to the city's popular boozer, Wunderbar. 

The watering hole, which has two venues, one in the city centre and the other in the West End, welcomed the group to allow Alastair to continue celebrating his birthday.
