Taylor Swift is rumoured to have had a helping hand in the bust department after faunting a noticeably fuller cleavage recently.

The 'I Knew You Were Trouble' songstress is alleged to have got a subtle breast enlargement by Dr. Michael Fiorillo, in a US report.

Maybe Taylor's rumoured boob job was an attempt to please her now ex-boyfriend Harry Styles, who she split from earlier this month.

According to sources, Taylor is desperate to get the 'Kiss You' singer back and has been left a "a wreck and torn up" following their split.  Insiders say that Taylor has been bombarding the 1D singer in a bid to win him back.
