Rochelle and Marvin Humes, Holly Willoughby and Paddy McGuinness turned out to watch Dec, 38, and Ali say ‘I Do’.
A heavily pregnant Fearne Cotton was also present – and she took to Twitter afterwards to praise their nuptials.
She gushed: “Watching someone you love get married is magic. Ali and Dec, your wedding yesterday was a dream [sic].”
Dec and Ali married at a church in his hometown of Newcastle on Saturday, and he shared a snap of his best man Ant, 39, driving him to the church.
He joked: “Morning! I know I’ve got somewhere to be today but I can’t for the life of me remember where… [sic].”
Alongside the photo of Ant, Dec added: “Slow down man, what’s the hurry!? [sic].”
Thankfully the presenting duo made it to the church on time, despite their joking.
Taking to Twitter later in the day, Dec thanked fans for their well-wishes.
He wrote: “Thank you for all the kind and lovely messages, they are appreciated.
“My wife and I had the most amazing, magical, wonderful day. D x [sic].”
Ali has managed the real-life besties for most of their careers, and she and Dec started dating in 2013.
