Famous Kids Who Played a Starring Role in Their Parents' Weddings

Harry Styles had the performance of a lifetime this past weekend — playing Best Man at his mum's second wedding! The 19-year-old One Direction singer walked mother Anne Cox down the aisle as she married longtime partner Robin Twist, who helped raise Styles after his parents divorce (when he was just seven years old). The nuptials took place at Pecks Restaurant in Chesire, England.

The 19-year-old "Kiss You" and "That's What Makes You Beautiful" crooner shared the honorable title with his step-brother, Mike, while his sister, Gemma, acted as Maid of Honor. He and the groom wore matching suits from Burberry for the special occasion, accessorized with a white rose on the lapel (to match Mom's bouquet).

As if the whole thing couldn't get any sweeter, he reportedly sang "Isn't She Lovely," which was his audition song for X Factor, the show that catapulted the band into stardom! Swoon. According to The Daily Mail, Styles has always been vocal about his close relationship with his mother, saying, "I tell her everything and she knows the truth."

Watch a short video of the wedding festivities on Vine, which he captioned "#chinching," a new term for gobbling down different types of food. His social media-savvy mom tweeted, "That was a PERFECT day."

Here, more celebs who helped Mom or Dad say their "I do's":

Kassius Lijah Marcil-Green: Brian Austin Green's son was the only guest present at his wedding to Megan Fox at Hawaii's Four Seasons Resort Hualalai on June 24, 2010. The former 90210 star asked him to be his Best Man. Clad in an all-white suit, he held a conch and proudly stood next to his father during the beautiful sunset ceremony.

Ava Elizabeth Phillippe: Reese Witherspoon broke tradition when she wore a blush wedding gown at her second wedding to Hollywood agent Jim Toth on March 26, 2011. Her daughter Ava (now 13) was the Maid of Honor, and she was the spitting image of her Mom that day, custom Monique Lhuillier dress and all. "There was a real family feel," a guest told People when asked about their Southern-inspired fête in Ojai, California.

Sophie Simmons: That same year, Gene Simmons' teenage daughter supported her rockstar dad when he married Shannon Tweed-Simmons on October 1 after 28 years of dating. High-powered vocals must run in the family — the MOH sang Etta James' classic ballad "At Last" for the first dance, and the entire experience was documented on the reality show Gene Simmons Family Jewels.

Tell us: Were you the Maid of Honor or Best Man at your Mom or Dad's wedding? On the flip side, would you ask your mother or father to be your MOH or Best Man?
