Madonna joins sexy-celebs-in-their-60s club

If anyone could put the "sex" in "sexagenarian" it would be Madonna.

The iconic singer turned 60 Thursday and celebrated on social media.

"In case someone forgot," she wrote in a caption on a photo of herself which included a "birthday" hashtag.

There were also plenty of tributes to the pop star.

"Happy birthday to Lady @Madonna!!!," singer Kylie Minogue tweeted. "I'm 14 years old, dancing and singing in my bedroom and she was just WOW!!! What a force and an inspiration. Enjoy your day Madonna!!!"

But Madonna is not the only one repping the fabulous 60s in style.
