Avril Lavigne and her ex-husband Deryck Whibley may be divorced, but their relationship still has a happy ending.

The "Girlfriend" singer, 39, invited her ex-husband and fellow Canadian rocker Whibley, 44, on stage during her Greatest Hits Tour at the MGM Grand on Saturday night June 1 in Las Vegas to perform Sum 41's hit song "In Too Deep" with her.

"Please give it up for Deryck from Sum 41," Lavigne said in a video compilation of the performance she shared to Instagram on Munday, June 3. There appeared to be only love between the exes, who shared hugs before and after their duet of the song.

The former spouses married in 2006 when she was 21 and he was 26. When they announced their split in 2009, a source told PEOPLE the marriage ended because Lavigne realized she was too young to be a wife.

Whibley opened up exclusively to PEOPLE in April about his decade of sobriety and life today.

During the conversation, the Sum 41 frontman spoke about the pressure he felt with the paparazzi's attention on his relationship with Lavigne at the height of their respective careers.

"I hated all that stuff," Whibley said. "I'm better now than I was -

back then, but I've always been a more quiet, shy, homebody person. I don't mind being out there on stage and promoting music and doing as much work as I can to push Sum 41's music, but the second it was on something personal, I really hated that part and really found that uncomfortable and really difficult to navigate. I wasn't very good at it."

He married his wife Ariana Cooper in 2015; the couple have two young children.

As for Lavigne, she admitted on the Call Her Daddypodcast in May that she never exactly dated throughout her career, but jumped into serious relationships instead (she broke up with Tyga for good in October 2023).

The Grammy-nominated "Bite Me" singer said she's a  she’s “f---ing awesome” partner in a relationship.

“I would date me. I cook. I'm a really big cook, really big into, like, the house and decorating, and I have a lot of fun with that," she added to host Alex Cooper.
