Are Gwen Stefani and Blake Shelton heading down the aisle soon? The No Doubt singer was asked about rumors she and the “Sangria” singer are planning on tying the knot soon, and Stefani gave a cryptic response, refusing to confirm or deny the speculation.

During an interview Thursday on “The Ellen DeGeneres Show,” the daytime talk show host asked the “Used To Love You” singer when she was getting married so could adequately prepare her schedule for it. “Oh, you’re crazy,” Stefani responded, laughing. “I’ll let you know.”

TMZ reported last month that Shelton and his girlfriend hired celebrity event planner Jerri Woolworth to help them start planning their nuptials. However, before Shelton and Stefani make their way down the aisle, they have to get engaged first.

Sources told Life & Style magazine that Shelton, 40, plans to propose to Stefani, 46, during an upcoming vacation in Mammoth Lakes California or during a trip to Aspen, Colorado. “Naturally, she’ll say yes,” the source said. “They’ve been talking about getting married for months.” According to People magazine, Shelton and Stefani’s friends are confident that an engagement will happen fairly soon. “They are not engaged yet,” a source said. “Everyone is expecting it to happen at some point, though. Gwen is very, very happy with Blake. She always acts giddy when she talks about Blake.”

Last week it was reported that the happy couple plan to marry before the year is over, but have not told their family and friends a wedding date yet. Us Weekly claims Stefani is going for a more “low-key” ceremony, and the wedding would most likely take place at Shelton’s ranch in Oklahoma or in the backyard. “Gwen doesn’t really care, she is just in love with Blake and their life together,” the source said.

Shelton and Stefani, who collaborated on the song “Go Ahead and Break My Heart” together, started dating last November while filming Season 9 of NBC’s “The Voice.”
