They have had rumors swirling for a while that they are planning to marry at Christmas later this year, and Gwen Stefani has done nothing to quell those rumors, simply telling Ellen DeGeneres during a recent appearance on her show that she would "let her know" when the wedding date was.

Stefani appeared on the Ellen DeGeneres Show to discuss her recent This Is What The Truth Feels Like tour, which has wrapped up, and the show host decided to try and grill her about her romance with Shelton, and when the two would be marrying, under the guise of needing to know in advance so she could block out the day on her schedule.

"Before I make plans because I make plans way ahead of time, tell me when you're getting married...I just need to know so I can clear that schedule," she said.

"Oh you're crazy," Stefani replied with a giggle.

"Just let me know," DeGeneres said.

"Okay, I'll let you know," Stefani added.

"No. Now," DeGeneres deadpanned.

Neither Shelton nor Stefani has outright confirmed or denied the rumors they were planning to marry.

The pair went public with their relationship in November of last year, a few months after each announced respective divorces. Shelton and Miranda Lambert announced they were divorcing after four years of marriage in July, on the day their divorce was finalized. Stefani announced a divorce from Gavin Rossdale after 13 years of marriage a few weeks later.
