The 'Voice' co-stars - who both split from their spouses this year - recently confirmed they are dating and things are said to be getting so serious that Blake wants to spend the holiday with Gwen and her children, Kingston, nine, Zuma, seven, and Apollo, 20 months.

However, according to Us Weekly, Gwen has not yet decided if she will take her new boyfriend up on his offer.

Meanwhile, Gwen, 46 and 39-year-old Blake are also considering spending part of the Christmas holidays together but she might also spend part of it with her ex Gavin Rossdale, 50, in order to keep things "as normal as possible" for the children.

An insider previously explained: "It's very likely they will be together for some parts of it, but Gwen still wants to have the holidays as normal as possible because of her kids. So Gwen may do a more traditional holiday with Gavin when their kids open up the presents, but it's clear to her children they are not with each other in any romantic capacity."
