The 'Shake It Off' sensation is genuinely becoming everyone's favourite party guest these days. Following her rocking rendition of her aforementioned hit single with Sir Paul McCartney and Jimmy Fallon during 'Saturday Night Live' 40th anniversary celebrations, she joins the latter on 'The Tonight Show' in a spot of exuberant dancing.

In a sketch entitled 'NYC Fan Dance Cam', clips of Swift and Fallon performing some crazy dance moves after throwing their popcorn all over the bleachers at a variety of sporting events in New York are interwoven with genuine footage of other sports fans being caught on Jumbotron, moving their bodies to the likes of 'Cotton-Eyed Joe' and 2 Unlimited's 'Get Ready For This'. 'Nice casual walk down memory lane', a panting Swift quips afterwards.

It had only been a matter of days previously that Fallon and Swift had rubbed shoulders, getting on stage together alongside former Beatle Paul McCartney to perform 'Shake It Off' and 'Saw Her Standing There' at The Plaza Hotel were the SNL 40 after-party took place.

The actual 'Saturday Night Live' episode provided more entertainment from Swift, when images emerged of the singer looking less than impressed at the seating arrangements while she watched the show. She was seated next to Republican politician Sarah Palin, and was apparently seen rolling her eyes at her during the show. However, it was later suggested that this was merely the media creating rivalry where there wasn't (despite Swift being a huge fan of President Obama) when it became clear that that particular shot was taken while various other members of the audience also had their eyes rolled up, looking up at a screen. It wouldn't be the first time her facial expressions have betrayed her discretion, though.

In other news, it looks like Fallon, McCartney and Palin aren't the only people who're getting to enjoy the singer's company, as it was recently announced that she was granted the position of Maid Of Honor at her best friend Britany Maack's forthcoming nuptials.
