Kathy Griffin has no problem going makeup-free around her boyfriend.

The 51-year-old comedienne looked nearly unrecognizable on Wednesday while going for a hike at Runyon Canyon in Los Angeles, but she proudly flaunted her makeup-face for photographers.

Griffin had a huge smile on her face as she held boyfriend Randy Bick's hand during their workout. The outspoken star wore a "Jimmy Kimmel Live" T-shirt, blue running shorts, sneakers and styled her hair in a messy bun on top of her head. Bick matched his girlfriend in a blue shirt, athletic shorts and black sneakers -- and a big grin!

According to Daily Mail, Bick, 33, and Griffin have been dating for quite some time but only took their relationship public the beginning of this year.

"I truly tried to keep [the relationship] under wraps," Griffin told Daily Mail. "He's a really nice normal guy with a nice normal job who doesn't care for the spotlight, and I like it that way and he does too."
