"What a fun time and wonderful photos to commemorate Elijah's favorite thing!" Perlman said in a Facebook post. "I am so glad Elijah will have these special photos to treasure with his GREAT Grandparents!"
Since she posted the photos to Facebook on Tuesday, they have gone viral. As of Thursday evening, the post had been liked 1,100 times.
Elijah's twin sister, Emilee, also had a birthday photo shoot. She opted for a princess theme.
Perlman was diagnosed with cancer shortly after her twins were born and when her older child was 5, she told CBS News. She's now in remission, and wanted to celebrate her twins turning 5 in a big way.
"It's a celebration for me and them!" she said.
