Uncle Harry has entered the chat! Harry Styles’ sister, Gemma Styles, took to Instagram on Friday (Feb. 23) to reveal that she has given birth to her first child, a baby girl, with husband Michal Mlynowski.

Gemma concluded her message by addressing those with fertility issues, writing, “I know that this news can be difficult for many people and I’m sending you lots of love.”
