Niall Horan’s has toasted the first birthday of the One Direction star’s nephew today.
Young Theo is being spoilt rotten by the Mullingar singer’s brother Greg and wife Denise.
And Niall said: “Happy 1st birthday Theo! Love you, have a great day buddie! Remember the day you were born very well.”
He also posted a picture of a car that he brought Theo online, writing: “They see me rollin! They hatin!”
It comes after his brother Greg started the celebrations before Niall arrived back in Ireland.
He said: “Wahoo happy first birthday too my amazing and beautiful son and best friend. You’re my life and I love you more than life I love you Theo.”
Already 1D fans have gone mad – with one showing off specially painted nails for the occasion.

They have also been inundating Theo’s official Twitter account – which has more than a million followers – with requests for a Theo magazine.
A source said: “Niall knows nothing about it. He is believed to be not too pleased that these coins are going to be sold to thousands of fans in his nephew’s name.”

When announcing the plan, Greg said that members of the Horan family would deliver a number of the coins to buyers’ homes.
Yesterday Greg also told of the moment his brother – who is expected to return home for Theo’s birthday – drove him to the hospital.
He said: “This time last year Tuesday morning Niall was driving me to hospital for the emotional wait for my baby boy.”
