Justin Bieber had a relaxing mother-son excursion with his mother, Pattie Mallette.

The 22-year-old pop star and his mom got pampered with pedicures on Monday, along with rapper Yung Killa. "Moms and k," Bieber captioned a photo from the nail salon.

The outing comes just a few weeks after Mallette, 40, attended her son's concert at the Staples Center in Los Angeles, California. "What a great show @justinbieber!!!!" the proud mother tweeted at the time.

A source also told ET that Mallette left Hawaii, where she lives, to meet her son in Canada a few weeks ago.

Mallette and Bieber have been spending more time together this year, but the "Sorry" singer did admit no too long ago that he was estranged from his mother for a bit. In an interview with Billboard magazine last November, he blamed his deteriorating relationship with Mallette on his headline-making bad behavior.

"I was distant because I was ashamed," he said. "I never wanted my mom to be disappointed in me and I knew she was. We spent some time not talking, so it takes time to rebuild that trust."

ET caught up with Bieber's mom in February 2013, and she too confessed that she wasn't always a fan of her superstar son's life choices, particularly, his multiple tattoos.

"That's one of those things that I don't necessarily have to like," Mallette said, also acknowledging at the time that her son is legally an adult. "He's going to make his own decisions."
