The 19-year-old lothario reportedly has a host of beauties awaiting his arrival when he and One Direction visit the US next month on their 'Take Me Home' tour, and as well as Ke$ha and Rihanna Rod Stewart's daughter Kimberly is keen to see him again after they spent a night together in Los Angeles last month.
A source told The Sun newspaper: "Ke$ha loves his accent, Kimberly bonded over dinner with her dad Rod and Rihanna's just a flirt."
Despite his renowned womanising ways, Harry is keen to focus on performing with the group - also made up of Niall Horan, Zayn Malik, Louis Tomlinson and Liam Payne - instead of picking up girls along the way.
The source added: "Harry's focus is on fun, not a girlfriend. The boys are on the road until November so a love affair isn't realistic."
Last week, Rod confirmed Harry had stayed the night at his LA mansion with Kimberly after having a meal with him, his wife Penny Lancaster and his 33-year-old daughter.
Rod said:"His [Harry] car was here in the morning. Let's put it that way. But he may just have come round to pick something up ... B******s! I let the cat out of the bag."
Harry - who was previously in a relationship with 23-year-old Taylor Swift - was swapping text messages with Ke$ha earlier this year.
The 'Die Young' singer revealed: "We've texted here and there. No sexting - not yet. Maybe he can be my cougar bait."
Ke$ha, 26, is convinced if she hooked up with Harry - who famously likes older women - it would be great.
She said: "It could be really fun ... I'm kind of a sucker for (British) guys. It's the accent. Harry Styles is pretty cute - he looks like a young Mick Jagger."
