Los Angeles: The Beatles star Paul McCartney's ex-wife Heather Mills feels he is not famous anymore and claims the musician is collaborating with young stars Kanye West and Rihanna so that people remember him.
The 47-year-old former model officially ended her six-year-old marriage to the surviving member of The Beatles in 2008, reported Aceshowbiz.
"When I go down the street, I get kids coming up to me - half of them don't even know who he is," Mills said during her appearance on Ireland's "The Late Late Show with Ryan Tubridy".
"That's why he's got to do songs with Rihanna and Kanye West, so people remember (who he is)."
Rihanna's latest song "FourFiveSeconds", featuring McCartney, 72, has peaked at Number 4 on Billboard Hot 100.
McCartney has collaborated with West, 37, on "Only One" and "All Day" that will be featured on the rapper's own full-length "So Help Me God".
