Coldplay helped a fan with a proposal during their concert at London’s Wembley Stadium on Aug. 22, but frontman Chris Martin had a few questions first. A video shows Martin joking around with the fan before honoring his request.

Martin joked that he needed to “do some basic security checks” when a fan tried to propose at his show in London.

The singer took extra precautions to avoid repeating a certain viral kiss-cam moment during the band's concert at Wembley Stadium.
