Eirianedd Munro (often called "Eiri") is an artist and former influencer who met Adam while studying at Loughborough University in 2019. The pair share a son named George, who was born in September 2020.

During Adam's 2021 stint on Strictly Come Dancing, viewers speculated about a "near-kiss" with his professional partner Katya Jones at the end of an intense Argentine Tango. Eiri lightheartedly mocked the widespread rumours on TikTok.

Although the "Strictly curse" was heavily rumoured, Adam's brother later clarified that the show had nothing to do with their separation. The couple officially broke up in August 2022, with Adam issuing a statement apologising for "letting [her] down".

Following their breakup, Eiri stepped back from public social media to raise their son, maintaining a strong bond with Adam's family, and remaining supportive of his new relationship.

Eiri publicly praised Adam's now-wife, Holly Ramsay, describing her as a "wonderful stepmother" to George.
