Katy Perry

“I’ve got boobs and I’m not going to chop them off, so I guess people will always talk about them,” she has previously remarked. Which is precisely what has happened throughout Katy Perry's career - including famously getting her scenes cut when she performed a riotous sing-a-long with show favourite Elmo on Sesame Street . Too much boob, not enough learnin according to some concerned parents.

Katy Perry's place as one of pop’s hottest faces is assured. Debut album One Of The Boys sold over a million copies, as did follow-up Teenage Dream and, with saucily attired live performances regularly playing to sell-out crowds, her success shows no sign of slowing down.

Then, of course, there’s Brand. When Katy Perry and the Dickensian wit appeared in public as a couple, some people called it a marriage of convenience. But we liked to think it was love - we’re old fashioned like that. Turns out, it didn’t work for whatever reasons, so the couple have separated. Sads. But Perry will survive - while Brand was gallivanting around with his new girlfriend, she released Part of Me, a breakup ballad that doesn't so much vilify him as big up herself. Oh, and she joins the Marines in the video, too. Not sure what to make of that.

Beyoncé Knowles

By far the hottest prong of Destiny’s Child, Beyoncé has gone on to become one of the most marketable artists ever, towing just the right line between philanthropic Christian wonder woman and ‘bootylicious’.

Beyoncé Knowles' marriage to Jay-Z helped, of course, elevating her to hip-hop aristocracy and making her probably the most heavily guarded women on the planet. You can still touch her though. In Madame Tussauds.

The Queen B’s success can be measured in other, less waxy ways. Beyonce’s sold upwards of millions and millions of records. She’s been named artist of the decade. She has a university course named after her, and a monument in Texas, her home state. But perhaps the most significant sign that she is something special, is that someone was nice enough to name a horsefly after her, Scaptia beyonceae.

The Carter family has now grown again. Just imagine being Blue Ivy Carter, the couple's first collaboration in a sentient being – a child so privileged she makes the royal family look like inbred hermits. She’ll want for nothing, but Jay and B won’t let her become spoilt. She’ll have enough money to do something, but not enough money to do nothing. Because Beyoncé is power, and we respect her so much, we’re not even going to make a crass joke about breastfeeding.
