The Gavin & Stacey comedian "sort of fell in love" with Beckham and his family after the pair filmed a Sport Relief sketch together last year.
The Mail On Sunday now reports that Corden is hoping to have the England star by his side when he weds fiancée Julia Carey in 2012.
When asked who he was considering for the important role, Corden enthused: "David Beckham would be awesome and I think I’ll be asking him. The Beckhams are such a great family."
Corden proposed to Carey on Christmas Day 2010, three months after the couple confirmed that they were soon to become parents.
Beckham is also expecting a fourth child with his wife Victoria.
