Jennifer Lopez is getting noticed for her lovely locks.  The new "American Idol" judge is taking top honors among women in the 17th annual Sally Beauty Best Tressed Survey.  Also earning recognition is pop superstar Beyoncé, whose 'dos in 2010 gives her the number two spot on the list.  Singer Katy Perry rounds out the top three among the ladies.  "Blue Bloods" star Tom Selleck  commands the men's list, ending George Clooney's multi-year reign.  Actor Ryan Reynolds and teen heartthrob Justin Bieber's hair also make the "cut."  Also earning recognition is Halle Berry, whose short style is the overwhelming favorite in the pixie cut category.

Lady Gaga once again leads the way with hair don'ts rather than hair dos.  Her outrageous looks earn her the title of Worst Female Hairstyle in 2010 (Female) for a second consecutive year.  David Hasselhoff has the number one spot on the men's worst list.  Dolly Parton, Miley Cyrus, Bret Michaels, and "Jersey Shore's" Paul "Pauly D" DelVecchio have also made the lists of less than desirable 'dos.
