But Ant took time out of his busy schedule to wish his best mate a happy 44th birthday... but not in the way you would imagine.
Ant, 43, took to Twitter to share an image of him dressed in a Marge Simpsons t-shirt and wearing a Marge Simpson wig.
Marge is the largely-bouffanted character from hit animated comedy series, The Simpsons.
I had to quickly get a birthday photo out there to celebrate the little fella’s big day!!
Flashing a cheeky smile, Ant wrote: "I had to quickly get a birthday photo out there to celebrate the little fella’s big day!!
"You’re welcome Declan!! Love The slightly bigger fella A"
Ant had used the same photo to wish Dec a happy birthday last year, and the Tweet had many of the joint account's 6.7million followers in bits.
"I was waiting for this tweet!" one wrote.
Another guffawed: "hahahahaha love it !!!"
"Awww you two just make my day!! X" a third wrote.
Ant not only has Dec's birthday to celebrate, things seem to be going well with his partner.
It's been reported that he girlfriend Anne-Marie Corbett are about to take a huge step in their relationship.
Ant will be heading back to I'm a Celebrity after missing last year's series as he battled alcohol issues and prescription drug addiction, and Anne-Marie will reportedly be joining him.
According to reports, the presenter wants his 43-year-old girlfriend - who is also his sober coach - by his side while he films in Australia.
