Robbie Williams has snubbed the idea of joining the Take That reunion tour to perform with the Pet Shop Boys. Williams was set to join his old boy-band mates for at least one of their forthcoming UK live shows (and there were even rumors that he would appear as a hologram), but he backed out saying he's too busy. The hunky star has reportedly been spending time recording a new album with the Pet Shop Boys, and is said to be planning to join them for a secret concert in London as well. Robbie decided to make a "Kylie style" dance album to please his gay fans. Hell, all he has to do to please his gay fans is be shirtless as much as possible and well, you know, have sex with us.

Madonna has reportedly posed for a series of racy pix that will drop in W magazine very soon. The omnipresent Madge is set to appear on a staggering 58 pages when the issue comes out, and she'll be dressed as a horse rider for the shoot. The images, shot by celebrity photographer Steven Klein, feature the star posing topless, wearing fishnet stockings, leather gloves, and a riding crop. A source said, “In one shot she's dressed as an English horse rider but there is a sexy twist as she has her boobs out." OK, so seeing Madonna's boobs is kind of old hat to us, but are we ready to see the almost-60 year old boobs of none other than Cher? If so, brace yourself: Cher recently announced she is planning to celebrate her 60th birthday this month by posing naked for a photo shoot. Meanwhile, she's also set to replace Celine Dion in Las Vegas, having been offered a whopping $60 million to take over the glitzy show at Caesar's Palace when Dion's run comes to an end. Bosses are even reportedly planning to build a unique concert hall to house Cher's spectacular show when she takes up residence in 2008. The deal means she'll be rubbing shoulders with a host of music legends, including Barry Manilow and Sir Elton John, who is a frequent guest performer in the gambling mecca

A few issues ago we reported on the ballooning weight of Janet Jackson, but recent paparazzi pix show she has slimmed down considerably. Word on the street is that Janet has recorded a song for her new album, 20 Years Old, with Khia, the infamous Southern rapper most famous for her racy hit single “My Neck, My Back (Lick It).” The new duet is called “So Excited” and will appear on Janet's upcoming release, but it won't appear on Khia's upcoming Gangstress CD, which hits stores July 11. No release date has been set for Jackson's new album yet, though. And finally, congratulations to Ashlee Simpson on the birth of her brand new, bouncing baby nose.
