It's that time of year again!
"No-Shave November" is here, folks, and that means men around the world are growing out their mustaches in an effort to raise awareness about prostate cancer and other male cancer initiatives.
Some of Hollywood's most famous faces have decided to jump on the bandwagon this year and grow out their facial hair for a good cause.
Homeland star Damian Lewis sported some facial fur on the red carpet at the premiere of Romeo & Juliet during the 8th Rome Film Festival.
Lewis also took to Twitter to rally up fans to join the month-long endeavor.
"MOVEMBER! Find your inner spiv and grow a mo this month to raise awareness for Prostate Cancer," he said.
The Brit actor has also chronicling his 'stache growth on his Twitter page with selfies galore since the beginning of the month.
And Lewis isn't alone…
Clive Owen was also spotted sporting a new accessory: a perfectly manicured, slightly creepy looking mustache.
The Hollywood hunk debuted the look while running errands in New York City with another gentleman.
The 49-year-old is said to have grown the sliver of hair for his upcoming role in The Knick, a TV miniseries that's based around New York's Knickerbocker Hospital during the early part of the 20th century.
But these two aren't the only lads to grow out their ‘staches.
