Madonna's Secret 'Secrets'

Madonna leaves her London gym Monday morning wearing her M by Madonna sunglasses by H&M.

Later in the day, Madonna held auditions at Secrets Strip Club for a mini-film she will be shooting next month. The lap dancer girls reportedly read from the script and then performed a dance for her.

When Justin Timberlake was asked if he’ll be singing with her Madgesty during a recent Shrek 3 interview, he replied, “Possibly, yeah!”

Mr. J.T. added, “She’s Madonna…. It doesn’t get any cooler than that! We actually wound up with 5 or 6 REALLY good songs, some unfinished, some finished and were gonna go back in July and finish some more stuff”
