Knight got engaged to longtime boyfriend Harley Rodriguez while vacationing in Africa, and McCarthy and Wahlberg admit they're not sure what the couple’s plan is for the nuptials.

"He was in our wedding -- so maybe we could be," McCarthy shared of whether they might be involved in the big day. "I'm the maid of honor? I don't know, I don't know how it works."

"He missed our whole tour announcement last week to go get engaged, so he marches to the beat of his own drum," Wahlberg teased. "So we'll see if he let's us."

Meanwhile, McCarthy also took a moment to shout out Selena Gomez on the carpet, addressing the singer’s first public appearance since recently taking some “time off” to deal with anxiety and depression.

"Selena Gomez, believe it or not, has always had a soft spot in my heart," McCarthy explained. "She's going through a lot of stuff ... for her to keep going and enduring and being a class act, I feel like she's like a daughter."

"I'm rooting for her," she added. "She's up for Artist of the Year so -- my hat's off to her."
