Gwen Stefani reportedly wants to make a serious commitment to boyfriend Blake Shelton, but it's not marriage on her mind.

"Gwen has told friends that Blake is the one and wants to make it official by having a baby," a source told Hollywood Life.

"She doesn't want to rush, but later next year she would be happy to get pregnant... She wants to make that commitment to Blake, she is ready to take that step."

But at the age of 46, there is a big "if" involved. Stefani would reportedly need to make sure "it is safe" to have another child before trying since it could be risky.

Stefani, a coach on The Voice with Shelton, already has three sons with ex Gavin Rossdale -- Kingston, Zuma and Apollo. She just delivered Apollo last year, and they all reportedly "adore" Shelton.

Stefani filed for divorce from Rossdale, who allegedly had a long-term affair with their children's nanny, right around the same time Shelton was finalizing his divorce from country star Miranda Lambert.

Stefani and Shelton then confirmed they're dating right after Halloween once multiple photos surfaced of the couple engaging in PDA and spending a lot of time together.

Over Christmas weekend, Shelton and the No Doubt songstress attended a Cardinals football game in Glendale, AZ. They took adorable selfies together and appeared to have a blast.

"They were sitting close and holding hands at a point. They were extremely friendly to fans, players and the people around them," an insider told E! News on Monday. "Blake loves football and is a big fan of the Cardinals so it was nice that Gwen saw him in his sport element."

The insider added, "You could see how in love they are with each other. Gwen was smiling ear to ear throughout the whole game!"

Meanwhile, reports are currently circulating Lambert has been dating singer and musician Anderson East for about a month now.

One source told Us Weekly, "They are really enjoying each other's company," and another insisted, "She couldn't have picked a better dude to have fun with. Anderson is the coolest guy."

Lambert ironically started following Stefani on Twitter recently, which could serve as a peace offering since she's found a new man or an indication she'd still like to keep tabs on her ex-husband and his new flame.

The Voice's tenth season will star Christina Aguilera instead of Stefani. Shelton has publicly expressed his sadness over the fact, saying he wishes there could be five coaches on the panel because he doesn't want his girlfriend to leave.
