Thanking the two "amazing mothers," the 26-year-old wrote: Double special day today thanks to 2 very special ladies and a very special little man... 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."

The "Light's Out" singer then wished his son on his third birthday, writing: "Happy birthday little man! 3 already I can't believe it. 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."

Meanwhile, Cheryl took to Instagram stories to thanks everyone for sending birthday wishes to her son, while also requesting her followers to practice self-quarantine amidst coronavirus pandemic.

"Thank you to everyone who's sending birthday wishes. He's three today. Obviously no party, but it doesn't matter, he's still having lots of fun, lots of cake, lots of toys. Hopefully in the summer, if we all STAY HOME, we can have a celebration of both... rid of this horrific, horrible virus and a late birthday party," the 36-year-old said.
