Spencer and Lauren were just some of the stars in attendance at the launch of new book, Mod: From Bebop to Britpop, Britain's Biggest Youth Movement.
The couple were all smiles as they posed for a photo at the party, which was hosted by British youth culture historian Richard Weight and Liam Gallagher's fashion label Pretty Green.
Spencer, who dressed casual in green check shirt, attended the bash alongside Little Mix star Jade Thirlwall and former Voice UK star Becky Hill.
Last week, Spencer's best mate Hugo Taylor told Reveal that Spenny has "never been happier" since finding love with Lauren.
"He's my best friend, I love him dearly and I've never seen him this happy," Hugo told us. "For me as a friend, especially around Valentine's Day, that makes me very, very ecstatic for him and I think that she is a wonderful influence on him."
