Liam Payne Celebrates Mother's Day in UK, Wishes Son Bear Happy Birthday

"Double special day today," he tweeted.

Liam Payne had two special occasions to celebrate over the weekend: Mother's Day in the U.K. and his son's birthday.

On Sunday (March 22), the former One Direction member took to social media to wish a happy Mother's Day to his mom, Karen, and to Cheryl Cole, with whom he shares 3-year-old son, Bear.

"Double special day today thanks to 2 very special ladies and a very special little man," he tweeted. "Happy Mother’s Day mum and Cheryl you two are the most amazing mothers Bear and I could have asked for, thanks for raising me right and thank you Cheryl for showing my son all the love in the world."

Payne went on to reflect on fatherhood and how quickly Bear is growing up.

“Happy birthday little man! 3 already I can’t believe it,” the 26-year-old added. “It’s amazing watching you grow and you surprise me constantly, it really seems like yesterday I was holding you for the first time, thank you for bringing life and joy to my world I hope I can do the same.”

Outside of raising his son, Payne recently released his debut solo album, LP1.
