The 'Boom Clap' hitmaker is helping out the 'Four Five Seconds' singer who is struggling to get her eighth album out through a lack of good quality material and the British star was more than happy to help out her ''favourite pop girl'' with her LP.
She revealed: ''I'm a really big Rihanna fan and I think she's such an incredible artist. She's my favourite pop girl. She's the real deal. I've actually been to a couple of writing sessions for Rihanna's new record. It was really fun to put together a couple of tracks.''
Meanwhile, the 23-year-old brunette beauty also shared that Hilton Hotel's heiress Paris Hilton inspired for her own album, the follow-up to 2014's 'Sucker' and she thinks her one-hit-wonder 'Stars Are Blind' is ''pop genius''.
She told the Daily Mirror newspaper: ''It's definitely the most electronic pop sound I've done. I've been really inspired by Paris Hilton, small dogs and a glitter, luxe lifestyle.
''I've never met Paris before, but we were both at the amFAR Gala during the Cannes Film Festival this year.
''I was performing and I saw her singing along to my song and I freaked out.
''I'm such a fan and one of my favourite songs ever is Stars Are Blind - it's pop genius.''
Corgan took to Instagram to confirm rumours of new Pumpkins material, saying the first songs could arrive as early as May.
