Heather Mills, the ex-wife of Paul McCartney took a shot at Paul during an interview on Ireland's The Late Late Show.

She said his recent collabs with Kanye West and Rihanna are a lame attempt to stay relevant.

"Half of [the kids] don't even know who he is.

That's why he's got to do songs with Rihanna and Kanye West, so people remember."

Mills added that, she finds, people are more interested in her career than his.

"When I go down the street," she told the show's host Ryan Tubridy, "It's 'Oh my god! You're a ski-racer,' or 'You help the animals.'

You know," Mills added, "I own the biggest vegan company in the world."
