Happy Birthday to Niall Horan's nephew, Theo, who turns one today. Where does the time go, honestly? Proud Uncle Nialler posted the most adorable pic of Theo tearing it up in a pretty hot new car. We're slightly jealous of his sweet ride, as he tweeted: "They see me rollin! They hatin!"
Niall also wished the little lad a happy birthday, remembering the day he was born fondly, as he wrote on Twitter: "Happy 1st birthday theo! Love you,have a great day buddie! Remember the day u were born very well. #HappyBirthdayTheo"
Niall's brother, Greg took to Twitter to send his birthday wishes too, writing: "Wahoo happy 1st birthday too my amazing and beautiful son and best friend your my life and I love you more than life I love you Theo x x x"
Even Theo himself tweeted some big news, writing: "My mammy and daddy said I'm having a bouncy castle for my party on Saturday !!!" Well versed for a one year old, eh? Today, he thanked his followers, writing: Thank you guys I'm having the best 1st birthday ever big kisses xxx"
