'Obsessed' Dave Grohl dedicates song to Taylor Swift

Foo Fighters guitarist Dave Grohl recently confessed that he is very much obsessed with Taylor Swift and dedicated a song for her.

The 'Best Of You' musician said in an interview that his band recently performed 'Congregation' from their latest album 'Sonic Highways' in a recent competition, but before that he announced the rendition was in honour of the 25-year-old singer, the Mirror reported.

The 46-year-old American musician has also jokingly warned the 'Blank Space' singer to get a restraining order if his obsession with her becomes a bit much.
