The Scottish singer-DJ is so enamored with his girlfriend, loving each part of her body that he included her 'perfect toes' in the love song he wrote for her.

'It was really romantic, just him and an acoustic guitar, about how she's so rare in their world, love at first sight... there's a funny line in there about how even her toes are perfect!' a source told America's OK! Magazine.

Swift found the line hilarious, saying her toes are what she considers the ugliest part of her body. Well, if there is love, it casts out all imperfections.

Girlfriend is 25-year old Taylor Swift, singer, songwriter and multi-awarded artist. Her most famous songs are 'Red', 'Bad Blood' and 'Blank Space'.  Boyfriend is 31-year old Calvin Harris, singer and DJ. He has multiple hits in 'Bounce', 'Let's Go', 'We'll be Coming Back' and 'Feel so Close'. The two met through a mutual friend who introduced them.  They have been dating since February, but it was in May at the Billboard Music Awards 2015 that they made public their relationship. Swift one numerous awards, and at one point, giddily kissed Harris. 

There have been talks that Harris was going to propose to Swift soon. He has reportedly been eyeing a 10-carat Neil Lane diamond ring for the beautiful singer. And if there are two successful people getting hitched, talks about pre-nuptial agreement also abound. Swift is worth $ 200 million, and Harris is worth half of that.

Before there was Harris and songs about perfect toes, Swift had a few more high-profile relationships.  She was with Joe Jonas in 2008, Taylor Lautner in 2009, John Mayer 2009 - 2010, Jake Gyllenhaal in 2010, Conor Kennedy in 2012 and finally, Harry Styles of One Direction from 2012 - 2013.  Swift refers to current boyfriend, Harris,  as being the one, the right man.  Before 'Miss Perfect Toes', Rita Ora was the girlfriend of Harris from 2013 to 2014.
