Ed Sheeran has been sued for allegedly copying parts of Marvin Gaye's 'Let's Get It On'.

The family of the late Ed Townsend - who co-wrote the 1973 hit track with Gaye - have reportedly filed a copyright infringement lawsuit against the red head, and claim Sheeran's 2014 record 'Thinking Out Loud' was ''strikingly similar'' to the single in Gaye's thirteenth studio album, according to TMZ.

The lawsuit read: ''The defendants copied the 'heart' of 'Let's' and repeated it continuously throughout 'Thinking'.

''The melodic, harmonic, and rhythmic compositions of 'Thinking' are substantially and/or strikingly similar to the drum composition of 'Let's'.''

This news follows Sheeran's recent $20 million lawsuit by Martin Harrington and Thomas Leonard, who claimed Sheeran's single 'Photograph' is a ''note-for-note'' copy of their 20009 song 'amazing' released by Matt Cardle, which was filed on behalf of Richard Busch.

The lawsuit stated: ''The chorus sections of 'Amazing' and the infringing 'Photograph' share 39 identical notes - meaning the notes are identical in pitch, rhythmic duration, and placement in the measure.

''The songs' similarities reach the very essence of the work. The similarities go beyond substantial, which is itself sufficient to establish copyright infringement, and are in fact striking. The similarity of words, vocal style, vocal melody, melody, and rhythm are clear indicators, among other things, that 'Photograph' copies 'Amazing'.''
