See photos of Rod Stewart's 80th birthday celebration with his huge family

Thanks to Rod Stewart's 19-year-old son, Alastair, we've got some photos of the family celebration surrounding Rod's 80th birthday. The two-time Rock & Roll Hall of Famer hit that milestone on Jan. 10.

Alastair posted a series of photos of Rod, Rod's wife, Penny, and some of Rod's eight children and their partners, as well as his granddaughter Delilah, all goofing around on what appears to be a boat; the location of the post is marked Antigua. In addition to Alastair, the guest list included Rod's sons Sean, Liam and Aiden and daughters Ruby, Kimberly and Renee.

According to the U.K. paper The Daily Mail, the family is currently cruising around the Caribbean on a $150 million super yacht.

Penny posted a photo of Rod on Instagram Jan. 10 and wrote, "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 our hearts forever, I love you xx."

Rod wrote, "What an incredible journey it's been – from unforgettable moments on and off the stage to earning some truly special honors along the way. But above all, my greatest joy has always been performing for you. Cheers to the memories we've made and the ones still to come!"
