Mark Wahlberg and Rhea Durham are celebrating a milestone for their son.

On Sunday, the mom of four, 45, shared some humorous memories of son Brendan as the family celebrated his 15th birthday.

“Happy Birthday Benny! 🩵🎈The most kind hearted boy…..You’ve always been so curious and hilarious,” Durham began her tribute on Instagram.

“From dropping your pants at public parks when the urge to pee hit, to flooding our guest house bc you wanted to see what would happen if you covered the shower drain with toilet paper,to ‘hiding your Halloween candy in different spots so I wouldn’t throw it away.’ You’ve made us laugh your entire life 😜😂,” she shared. “I love you baby. Love, mommy ♥️1️⃣5️⃣❗️❗️❗️.”

In early August, Durham shared photos of her family in action on Instagram as they celebrated the “summer stuff” they did together.

One photo showed three of her four children in the pool, all staring at their dog who was watching them from the outside. Grace made the most appearances, from laying in the barn with her horse to paddleboarding with her pooch.

In other photos, Michael posed with big sister Ella, while Wahlberg adjusted Michael’s tie in another.

In the spring, Wahlberg opened up about his decision to depart Los Angeles to put the children first, saying that the move was working well.

“They love Vegas,” Wahlberg told E! News. “I spent lots of time in L.A. pursuing my interests and my career, and now it’s time for them to pursue theirs.”

He added: “Everybody is thriving there, it’s been great.”

Reiterating that the move was in an effort to “give my kids a better life and follow and pursue their dreams — whether it be my daughter as an equestrian, my son as a basketball player, my younger son as a golfer,” Wahlberg told The Talk, “This made a lot more sense for us.”
