Mandy Moore Learns the Hard Way Why You Shouldn’t Wear a Dress to a Kids’ Birthday Party

That said, the This Is Us star didn't let her wardrobe stop her from having a blast. 

By Jessica White

This Is Us star Mandy Moore is a mama bear to the bone.

How to Watch

Watch This Is Us episodes on NBC.

The actress, who played Rebecca Pearson on the beloved NBC series, is currently on the adventure of raising her two adorable sons, Gus (2) and Ozzie (9 months). That adventure sometimes includes birthday parties with Gus and Ozzie's friends — including one bash that Moore posted to Instagram about on July 30. 

The post in question is a delightful video of Moore and little Gus having a blast while sliding down a giant slide. Moore wore the loveliest plaid dress for the occasion, but she soon (hilariously) learned it wasn't the best attire for slide activities. Here's what happened:

In the heartwarming clip that Moore posted from the party, she and Gus sit together at the top of the massive slide. Moore pushes them forward, and down they go — but Moore's dress got the separate memo to fly upward. Oops! 

Moore handled this like a pro, of course, angling her fall to keep her dress in place while still holding Gus. The two were in a fit of giggles by the time they descended — proof the day was well-spent!

Moore had a sense of humor about her slight wardrobe miscalculation. "Don’t wear a dress to a kid’s birthday party 🤦‍♀️," Moore teasingly captioned her delightful IG clip. "Happy Bday, Bear!!! This was too much fun!!"

"These dudes rule my heart," Moore said of her mini-me sons. "Each night, Taylor and I fall into bed after we’ve put them down; after we’ve straightened up from the chaos of dinner/bath and set up for the next morning and we chat about the day…. And just how utterly nonstop and gratifying it is. You never know what the day will bring and you roll with it to the best of your ability, right? All of that to say, I wouldn’t have it any other way. I mean, I do look forward to feeling moderately well rested sometime in the next decade."
