Just days after a jury ruled that Pharrell Williams and Robin Thicke did commit copyright infringement with their 2013 hit Blurred Lines, it looks like the producer may have another legal battle on his hands.

According to Marvin Gaye's children, the producer also lifted parts of the late soul singer's 1966 song Ain't That Peculiar for his feel good 2013 smash Happy.

"I'm not going to lie. I do think they sound alike," Gaye's daughter Nona told CBS News.

Gaye's ex-wife Janis also claimed that there was no denying the similarities in both tracks.

"I heard the mash-ups – but I didn't really need to hear them," she said. "I know Ain't That Peculiar and I've heard Happy."

On Tuesday (10 March) a court awarded Marvin Gaye's estate and his three children nearly $7.4m (£4.9m) in damages after finding the musicians had plagiarised the late soul singer's chart-topper Got to Give It Up.

The ruling came after months of litigation in which Gaye's heirs claimed that part of his 1977 hit were lifted by Pharrell and Robin. In 2014 Robin testified that he was not present when the song was written, even though he received credit.

But despite looking over Williams' catalogue with a fine toothcomb, the family insists that there are currently no plans to sue over the Despicable Me 2 theme tune.

"We're not in that that space," Janis said. "We're just in the moment today and we're satisfied."

Suggestions that William's Oscar-nominated Song was also a Gaye rip off are not sitting well with the producer, whose lawyers have fired back in a statement.

Howard King said:"Pharrell has readily admitted that Marvin Gaye is one of his idols but it's silk and rayon. If this is the way the law is going to go then the creator of rayon better look behind him for lawsuits from the owners of silk, because even though they feel the same, they are structurally completely different, just like these songs."
