Edwards and Oxlade-Chamberlain welcomed Axel on Aug. 21, soon after Edwards' Little Mix group mate, Leigh-Anne Pinnock, gave birth to twins with fiancé Andre Gray on Aug. 16.
Edwards announced she was expecting back in May, writing on Instagram, "So happy to be on this wild journey with my soulmate. Me + Him = You 🌎♥️. We can’t wait to meet you baby Ox!"
Rumors that Edwards and Oxlade-Chamberlain were dating first began in November 2016, a year after the singer and Zayn Malik called off their two-year engagement. Edwards and Oxlade-Chamberlain eventually made their relationship Instagram official in February 2017 with a pic of them kissing in front of the Eiffel Tower.
