Everyone loves Adele, even if you’re the biggest pop star of our generation... right, Britney Spears?

Adele graces the cover of Elle magazine for its "Women in Music" issue, where they pretty much just dish on how perfectly perfect she is in every single way. Tell us something we don’t know, Elle. But it’s Britney’s open letter to the British singer that’s definitely the highlight of the whole issue!

Check out what Britney said after the jump.

Adele might be one of the most universally loved celebrities around, but that doesn't mean everyone likes her.

Case in point? Acid-tongued comedian Joan Rivers. The legendary comic has made a career out of calling it like she sees it, but has been recently criticized for being needlessly cruel towards the singer. She was booed on The Late Show with David Letterman while cracking jokes about Adele's weight, but that didn't stop her from flinging a second round of barbs during a recent interview.

Find out what she had to say after the jump!

Don't let Adele's fun-loving personality fool you: when it comes to business, she knows exactly what she's worth.

South African business tycoon Vivian Imerman asked the singer to perform at his daughter's wedding and she agreed, but for the hefty price of $3.73 million for a 25-minute set! In other words, she'd be making a cool $149,430 per minute. Needless to say, Vivian decided to look elsewhere for a performer.

But does this price tag make Adele the priciest wedding singer on earth? Check out our roundup of 9 other celebrities who will sing on your big day for astronomical sums.
