Lily Allen has set her sights on Jennifer Aniston's ex-boyfriend John Mayer - she's fallen for his "sexy" guitar skills.
The singer, who has dated musicians like Chemical Brothers star Ed Simons and The Streets' Mike Skinner, has suggested newly-single Mayer could be her next big beau after devoting a special message to him on her Twitter.com blog.
Allen writes, "I think I'm in love with john mayer (sic), I watched a DVD of one of his concerts last night, on the bus. His guitar playing is mesmerising. Sexy."
