Filming for TNA Xplosion, which currently airs on Challenge TV in the UK, the wrestlers were on hand to help out with the launch of the new TNA toys and sign autographs for fans.
JB said: "This was all organised through the power of Twitter and Facebook, so to see so many fans turn up made our day.
"I call these events Tweet 'n' Greets - and I'm pleased to say this topped the attendance of any we've done in America. Yet another record for our great fans in the UK."
TNA fan Danielle Risebury added: "I was especially pleased with all the personal touches and being treated so well by JB and Magnus, who took time to make every fan feel special."
