Fifth Harmony say they are addicted to Mariah Carey's new song.

The iconic US singer recently debuted the fresh track 'Infinity'.

It seems to have perked an interest in girl group Fifth Harmony, who wrote on Twitter:

"Can't stop listening to @MariahCarey's new single #Infinity."

Fifth Harmony sampled Carey on their 2015 song 'Like Mariah'.

Carey's new song meanwhile features on her upcoming greatest hits compilation ‘#1 To Infinity’.

The singer will also open her new Las Vegas residency at Caesar’s Palace on May 6.
