Ariana Grande served with copyright lawsuit

Ariana Grande is being sued for allegedly ripping off a pre-existing track for her hit One Last Time.

Songwriter Alex Greggs has filed a copyright infringement lawsuit against the pop star over the single, which was featured on Grande's 2014 album My Everything.

In the papers obtained by TMZ.com, Greggs claims Grande and producer David Guetta duplicated the chorus of his 2012 song Takes All Night, which he wrote for EDM artist Skye Stevens.

Greggs alleges the duo also plagiarized his lyrics, "Cause baby if it takes all night, I’m taking you home," with Grande saying in her hook, "I need to be the one who takes you home."

Greggs, who has worked with stars such as Lady Gaga, Justin Timberlake and both Michael and Janet Jackson, is seeking an unspecified amount of Grande's profits from the hit.
