After watching his best pal tie the knot, Dec has now revealed it made him wonder if he was ever going to find 'The One' just as Ant had done.
"I was envious, but I wasn't jealous," he said. "I would think, "Oh God, when's that going to happen for me?."
Speaking to Times 2, he added: "I was so happy for him, but I was like, 'oh god, that looks quite nice. I'd like that'."
Reflecting on Ant's wedding to wife Lisa Armstrong, Dec said it made him realise he wanted to marry himself one day.
"It made me look inwardly and realise that's what I wanted," he admitted. "[I wanted] to have a partner and get married, but it wasn't there at the time."
Luckily for him though, Dec has now found his future missus and is looking ahead to a wedding of his own.
Last year, Dec revealed he had got engaged to long-term girlfriend and manager Ali Astall, surprising fans and Ant - who claims he had no idea his BFF was going to propose!
Holidaying in Australia before the last series of I'm A Celebrity Get Me Out Here! aired, the TV presenter popped the question. Following his proposal, Dec told fans he was a "very happy boy" - aww!
Since then, Dec has revealed he and his wife-to-be are hoping to wed this summer.
Speaking backstage at the NTAs last month, Dec told Reveal he was keen to tie the knot sooner rather than later - despite having a busy year ahead.
"Hopefully I'll have time for a wedding," he joked. "We're hoping to get married in the summer."
