Perrie Edwards announced on Saturday that she is expecting her second child with fiancé Alex Oxlade-Chamberlain.

The singer posted a short clip on social media in which her four-year-old son, Axel, appears to kiss her visible baby bump. Edwards captioned the post, "Guess what hunnies…" and turned to reveal a white T-shirt bearing lyrics from her new single, "If He Wanted To He Would." Several of her celebrity friends left congratulatory messages beneath the post.

Edwards and Oxlade-Chamberlain, who are engaged, already share Axel. The couple has not released further details about the pregnancy, including a due date or how far along Edwards is.

The announcement follows a period in which Edwards spoke publicly about earlier struggles with pregnancy loss. On Paul C. Brunson's We Need To Talk podcast, she said she experienced two miscarriages before the birth of Axel, calling the losses "devastating." She has discussed how those experiences affected her before becoming a mother.

Edwards rose to fame as a member of the pop group Little Mix and has continued a solo career since the band went on hiatus. Her new single, whose lyrics she referenced in the post, is part of her recent solo releases.

Friends, fans and media outlets noted the family moment in the post, and several well-known figures in the entertainment industry publicly sent congratulations. Edwards has kept portions of her personal life private at times, while using social media and interviews to share milestones and challenges.

Neither Edwards nor Oxlade-Chamberlain provided further comment beyond the social media announcement. Representatives for the couple did not immediately respond to requests for additional information.

The couple's growing family marks another personal milestone for Edwards following her return to music and public discussion of motherhood and loss.
