The singers have teamed up for a new track,'Calling All Hearts', but Jessie has ruled out any naked antics like those in Robin's 'Blurred Lines' clip, which saw him surrounded by nude models.
She told The Sun newspaper: ''No boobs. Not doing that. Even though Robin is really cool and I was thrilled he wanted to duet with me.
''I'll be getting paid a lot of money if they want me to dance around like the girls in the 'Blurred Lines' video.''
The 'Wild' star also appears on the debut album by Dj Cassidy, which includes a number of classic artists Jessie is proud to be featured alongside.
Meanwhile Jessie says she's also proud her songs were nearly barred from hopefuls auditioning for talent show 'American Idol'.
She said: ''I met [former show judge] Randy Jackson last week and he said there was a point where they almost had to ban my songs from the auditions because everyone would come in and try sing 'Mama Knows Best' and 'Price Tag'.''
'Calling All Hearts' is included on Jessie's second album, 'Alive', which will be released next month.
Spencer Morrill believed he was in a relationship with the singer and that she was hiding messages for him in her songs.
Was the singer unknowingly taking counterfeit pain medication?
Roberts had left the band in 2012, due to problems with blood circulation and other health issues.
The popstar turned actress is back in the studio.
