Palmer attended the event with his parents and girlfriend, Connie Grace, a nail artist and manicurist from Manchester.
The Chelsea star and Grace were first seen together on vacation in Ibiza in August. The two were beaming as they rested on a boat and paddleboard on the waves. They have kept their romance discreet, but they were snapped holding hands at the PFA Young Player of the Year award in September before they were officially seen together as a couple at the GQ event at Kensington Roof Gardens on Tuesday.
