Looks like Harry Styles is a mama's boy.
The One Direction star served as best man at his mother's wedding over the weekend, which took place in the town of Congleton in Cheshire, England.
According to British reports, Harry's mum, Anne Cox, married longtime partner Robin Twist—who helped raise the boy-bander after his parents split when he was 7—in a quiet ceremony at Peck's restaurant Saturday. The location was kept top secret until the very last minute to keep Directioners at bay.
The British singer's 20-year-old sister, Gemma, reportedly served as the maid of honor, while Robin's son from a previous relationship, Mike, shared the best man duties with Styles.
Harry looked charming and handsome in a black suit, white shirt and skinny tie, rocking a white rose on his lapel to match his mother's bouquet (too cute!).
"Well what a lovely day Ta for everyone's good wishes, we're all very happy," Harry sis tweeted after the ceremony. "Only downside is, wearing 6 inch heels for 14 hours has caused me to lose all feeling in the toes on my left foot. C'est la vie!" she added.
The 19-year-old pop star also posted a Vine video from the fun-filled day, which features guests sipping champagne, eating cake and #Chinching, according to Harry's caption.
And apparently, all the excitement exhausted Styles and his sis: "All our lovely family and friends left this afternoon... and me and @Harry_Styles were asleep in the garden within 15 minutes. #naptime," she posted Sunday morning.
Aw, congrats to the entire fam!
