They are discussing the possibility of a future together, but don't necessarily expect to hear that Blake Shelton and Gwen Stefani tied the knot around Christmas anymore.

The pair have been rumored for a while now to be planning a Christmas wedding on Shelton's Oklahoma ranch, but haven't spoken out about the news. However, a new report suggests that while a specific date and plans aren't being hammered out just yet, the couple is ready to start considering it as a possibility for their future.

"If there is a wedding date, they haven't told their families yet," a source told Us Weekly. "They talk about their future and growing old together, but there aren't specific plans like a dress or flowers."

"Gwen has said they borh want something more low-key than their first weddings," the source added. "It would likely be at Blake's ranch [in Oklahoma] or in the backyard. Gwen doesn't really care, she is just in love with Blake and their life together."

Meanwhile, Stefani got flustered when asked point blank about plans to marry Shelton while appearing on On Air with Ryan Seacrest Friday.

"I don't know! God, I don't know. Everything is going so quickly," she said. "I'm in the moment and um-Look at me! You got me tongue-tied."

If the two were to in fact marry, either by this Christmas or at a later date, it wouldn't be their first marriages. Stefani split from ex-husband Gavin Rossdale last year after 13 years of marriage. Shelton was previously married to Kaynette Williams for three years until 2006, and Miranda Lambert for four years until last year.

Shelton and Stefani went public with their romance last November, while Lambert also went public with her relationship with singer Anderson East around New Year's this year. Rossdale has recently been reported to to be seeing Tiger Woods' ex-wife, Elin Nordegren.
