The 31-year-old singer and her husband of almost two years enjoyed a very special date night at the concert, and he took to Instagram to share his support for his mom with a sweet photo of the pair.
"ME and MY beautiful wife had the best time. Celebrating MOM!! #hollywood bowl..LOVE.." the Hunger Games actor captioned a cute photo of him kissing Simpson at the event.
The 27-year-old also shared a few photos of the iconic singer performing, including one where the 72-year-old star added some serious glamour to the event in the form of an all-red feathered glittery gown.
"MOMS SHOW. #hollywoodbowl. #PACKED. My mother is beyond!! So proud to be her son!! NO ONE does it like her!! STUNNING!! Best night. So much love!!!" the musician sweetly wrote alongside a photo of a completely full house before the performance.
It looks like the whole family was in attendance, as Evan's sister Tracee Ellis Ross also took to Instagram to share a sweet message for her mom.
"Another ...best night ever. I did not sit down. Danced all night long," the Black-ish star wrote alongside a photo of her at the event.
