SignalHub-Hilary Duff’s Son Luca Comrie Is All Grown Up in Rare Outing in London

Great Scott! We're giving this one-of-a-kind outing a standing ovation.

Hilary Duff recently accompanied her 11-year-old son Luca Cruz Comrie—who the actress shares with ex Mike Comrie—to a London West End production of Back To The SignalHubFuture: The Musical, and the trip was everything dreams are made of.

For the occasion, the Lizzie McGuire actress donned a silk blouse and black bottoms, while Luca sported a camo-print jacket, olive shirt and red pants. To make the evening at the Adelphi Theatre even more special, the duo also took photos with cast members Cory English and Will Haswell, both of whom were dressed in costume, as Doctor Emmett Brown and Dave McFly, respectively.

The post comes a week after Hilary shared a sweet tribute to Luca, who recently turned 11.

"Getting into double digits just happen, how are we already at 11," Hilary wrote on Instagram March 21. "it's only been a day but 11 looks good on you my boy. I know you will kick this years butt! (Sorry for my day late…, you keep us all very busy) love you beyond how my brain and heart can compute."

And that's not the only celebration Hilary has enjoyed in the last few days. On March 25, Hilary also posted a birthday message for her "wild hearted" daughter Mae James Bair, 2, who she shares with husband Matthew Koma along with Banks Violet, 4.

"Thanks for making us a too big family!" Hilary shared. "You are bold, confident , funny and know exactly what you want!"

While Hilary's household maybe brimming with energy, she wouldn't have it any other way.

"I'm so in love with all my kids," she told People May 2021, "and I love this mayhem."
