Sir Rod Stewart has assured fans he's 'not finished yet' as he marked his 80th birthday on Friday following 10-days of lavish celebrations.

The iconic singer took to his Instagram Stories with a sweet post thanking his 'loyal and rowdy' supports for their devotion over his 50-year career.

He wrote: 'May I take this opportunity on this my 80th birthday to personally express my gratitude and thanks to all my loyal and rowdy fans all over the world, for helping give me such a wonderful life!'.

'In return I hope I've given you some memorable songs and lively concerts... I've not finished yet. Sir Rod'. 

Meanwhile wife Penny Lancaster, 53, shared her own gushing tribute to her 'darling' alongside a san of the sun-soaked Maggie May hitmaker.

'Happy birthday my darling, so blessed to be sharing this day together with all our kids. Building more memories to carry with us into the future and to be held close to out hearts forever, I love you'.

The legendary musician is currently enjoying a 10-day holiday onboard a $150 million super yacht in Barbados as he spends quality time with his big blended family to celebrate his milestone birthday. 

Footing the bill for everything, the trip is already shaping into an incredible bash as his son Alastair Wallace, who he shares with wife Penny, took to social media with a selection of snaps. 

Scraping his locks back in a bun, the star wore a white linen shirt as he pouted in a cheeky mirror selfie before getting stuck in with golf off the back of the boat. 

He also shared a snap of the gang climbing a giant slide as they prepared to make a splash into the sea. 

The group were later seen all enjoying a group dinner as they waved their napkins in the air at La Guérite Beach in St Barths.

Rod, who has eight children by five women, has paid a reported $3million for a three-tiered super yacht which set sail on Sunday. 

Wife Penny is onboard with their sons Alastair, 19, and Aiden Patrick, 13, as well as Rod's daughter Kimberly Stewart, 45.

The TV personality and socialite has been sharing snaps from the lavish trip, including a picture of her daughter Delilah, 13, posing with Rod.

Her brother Sean Stewart, 44, is part of the party along with his girlfriend Julia Stambler. 

Rod's daughter's Ruby, 37, and Renee, 32, are onboard with their respective partners Jake Kalic and Adam Sumner, as well as Liam Stewart, 30, and his wife Nicole Artukovich, who is expecting their second child.

His grandson's Otis and Louie, both one, are also on the trip.

The luxury vessel, which reached St Barts on Tuesday morning, has a hefty crew, complete with three chefs ‘to take care of everyone’s dietary needs and restrictions’ as the famous family ‘hop across several islands’ in the Caribbean.

‘The holiday is costing Rod millions,’ an insider told DailyMail.com. ‘He’s known to be a cheapskate but not this time. He flew everyone to Florida first class and has told them they won’t need to put their hands in their pockets for a thing. He’s covering their every whim.

‘The reason behind the trip is Rod feels it’s time to bring his family together for his big birthday. There have been battles between many of them over the years. The singer wants everything from now on to be harmonious.’

The family kicked off the early celebrations by paying homage to Rod’s beloved Celtic FC on Sunday.

Sean, Adam, Renee, Jake, Alastair, Aiden, Julia, Ruby, Liam, Nicole, Penny and Rod donned the green and white pic for a group family photo. 

The Maggie May crooner shared the image on his Instagram, writing: ‘Early birthday celebrations.’

On Tuesday night the Stewart's enjoyed a night out, with Penny sharing a picture of them all outside a bar in the popular celebrity hotspot.

Julia, the founder of Skinsane, also shared several videos from the celebrations at cabaret club, Le Ti. 

Rod is no stranger to holidaying with his brood, having spent days onboard a luxury 197ft, £274,000-a-week yacht in Italy in summer 2022.

But insiders claim he wanted to ‘do it up big’ for his current celebratory adventure.

The Grammy Award winner chose the 288ft vessel which features nine suites for guests, as well as a beauty salon, a gym, a Hammam, a swimming pool and a helipad.

‘This trip meant so much to Rod,’ added a second source. ‘The whole family has come together and put any drama aside to really have a bonding experience. 

‘Being surrounded by so much love is invaluable to Rod. He wanted to do it up big for this one. 

'He could not have gone bigger.’
