Mark your calendars! Blake Shelton and Gwen Stefani are preparing to walk down the aisle this summer — and their good friend Luke Bryan just offered to officiate their wedding! In an interview with Entertainment Tonight on the ACM Awards red carpet Sunday night, the country singer announced he would be "honored" to marry the couple.

This news comes just days after Life & Style exclusively revealed that Blake, 41, and Gwen, 48, were tying the knot in Mexico after being inspired by the beachy location during Blake's recent performance at a music festival in Riviera Maya. Watch the video above for Luke's advice to his BFF before his big day.

Along with a wedding, the couple, who met on The Voice, also plan to surprise their guests with some baby news! "Her dream is to marry Blake and have his child. They’re both so overjoyed," the source said. "Blake and Gwen have been wanting this day to come for a very long time — being pregnant when she walks down the aisle is the ultimate wedding scenario for Gwen."

This shouldn't come as a huge surprise to fans, as Gwen, 48, recently gushed about committing to her boyfriend on The Ellen DeGeneres Show. "I think about [marriage] all the time," she said earlier this month. Her boys, Kingston (11), Zuma (9), and Apollo (4), are also expected to play a huge role in the ceremony.

"At this point in my life, I kind of had put [having kids] as like, ‘Well, that wasn’t meant to be.’ Then all of a sudden it happens — one way or another — and it’s like, ‘Wow, I really missed out on a lot,'" Blake said on The Today Show of his future stepsons. "And so having them around, is you know, I don’t even know how to describe it. It’s so much fun."

We'll be waiting for our invite.
