Hamish and Zoe's son, Sonny, celebrates his first birthday, is totally adorable

"We love nude businessman party baby VERY much."

"That moment your dad tells you not only have they already cast the latest Magic Mike movie, but they've also finished shooting it."

"Happy birthday, tough guy. I love you HARD."

"Whatever else is unsure in this stinking dunghill of a world, a mother's love is not." James Joyce

"Happy Birthday my beautiful boy. You've given us so much fun over your first year, and whilst I missed you very much for the 37 days you were conducting scientific research aboard the International Space Station, I understand it was important work for humanity and you were super excited to go, plus it gave us a chance to catch up on some house work and admin anyway. I would still be so proud of you even if you weren't one of the best astronauts of all time. Dad."

"Here's to the all time, hands down, greatest, most beautiful MILFT, @zotheysay (Mum I'd Like to Formally Thank)."

Guys look at this awesome birthday cake I made for Sonny! It's even got a tiny chocolate road with trucks spelling out his name! #proud #hardworkpaysoff

And by "made" I of course mean "asked @burchpurchese to please create because Sonny loves cars and trucks so much, and they are completely genius and I knew they would do something astonishing, which they did."
