Gwen Stefani and Blake Shelton are still going strong one year after going public with their relationship. Recently, the pair was seen out and about in Los Angeles together with Stefani's son, Apollo, and the pair looked relaxed and happy as they enjoyed the warm California weather on Wednesday, Nov. 16.

In photos published by the Daily Mail, the "Don't Speak" hitmaker wore an all-black outfit consisting of a sweater, an undershirt, and leggings while pushing her son's stroller, while the country singer donned a gray button-up shirt, blue jeans, brown shoes, and a cap for the outing.

The couple's excursion comes after the former No Doubt frontwoman gushed over the 40-year-old in her acceptance speech at Monday's Women of the Year Awards by Glamour magazine. An emotional Stefani thanked her fans for their support, and she also thanked "The Voice" coach for "kissing me back to life" after her divorce from Gavin Rossdale.

Now, all eyes are on the couple as new reports claim that the pair is looking to tie the knot next year. According to Radar Online, Stefani and Sheldon plan to make it official at the Church of the Good Shepherd in Beverly Hills on May 5, 2017, and it was claimed that couple has been trying to finalize their plans for the big day.

"They can hardly agree on anything!" said a source to the media outlet. "Gwen wants to go big on this — and Blake wanted to make it an informal affair down home in Tennessee or their new place in Oklahoma — but he's not willing to go to the mat against her."

The insider claims that the 47-year-old's guest list "was 700 people alone" and that Stefani allegedly wanted celebrity music stars to perform on their special day. However, the "She's Got a Way With Words" singer apparently does not want their wedding to resemble a music festival in any way.

The source said that the pair agreed to perform at their own wedding and that they will be singing Jon Bon Jovi's "Blaze of Glory" as a wedding song. As for the guest list, it has allegedly been scaled down to 400 guests and includes Jennifer Aniston, Justin Theroux, Courteney Cox and fiancé Johnny McDaid, Katy Perry, Keith Urban, Nicole Kidman, Luke Bryan, and Brett Eldredge.

The couple has yet to comment on the wedding rumors. Stay tuned for more news about Gwen Stefani and Blake Shelton.
