As the "Toxic" singer turned 33, fans were given a visual taste of her big day via Britney's Instagram and Twitter pages, including a picture of an especially detailed and personal cake designed by Britney's boyfriend.

According to E! News, Charlie conceptualized and personally decorated and designed Britney's birthday cake, which was topped off with an edible gold plate that said "Britney's Club 33," a nod toward the secretive, members-only restaurant inside Disneyland called Club 33. The cake topped off a weekend of fun that also saw her two boys wish their mommy "Happy Birthday" on the beach.

"Couldn't have wished for a better birthday yesterday… Hello, 33 #club33," she wrote on Instagram in a photo of her blowing out the candles on her personalized cake.

"Charlie has been a longtime client of Duff's Cakemix and he wanted to specifically design this for her from him," a source told E! News, saying he made the cake in the do-it-yourself cake decorating studio. "Every detail came straight from his creative, sweet brain."

"Charlie is a sweetheart. He put a lot of time and thought into this," the source continued. "You can see from the pictures Britney sent out that the colors were pinks and golds and blacks. It was all his creation!"

A tip of the hat to you, Charlie.
