Make-up free Kathy Griffin is unrecognisable as she enjoys a hike with toyboy beau Randy

It can be difficult for celebrities to go incognito on their days off.
But US comedienne Kathy Griffin certainly didn't have that problem on Wednesday, as she enjoyed a hike with her toyboy beau Randy Bick.
The 51-year-old star was unrecognisable as she went make-up free for the day out, piling her red hair on top of her head in a messy top knot.

Day off: Kathy's make-up free appearance is in sharp contrast to her usual red carpet glamour

Kathy's look is in sharp contrast to her usually picture perfect appearance for her frequent red carpet events, but the actress managed to show off her flawless complexion by leaving her make-up bag at home.
The pretty star also displayed her slim figure in her workout gear, wearing a Jimmy Kimmel Live T-shirt and a pair of grey shorts.
Kathy finished off her outfit with white ankle socks, and beamed happily as she clutched her boyfriend's hand while they strolled at Runyon Canyon.

Meanwhile, 33-year-old Bick seemed entirely unconcerned by Kathy's day off, make-up free appearance, looking thrilled to be spending time with his girlfriend.

The couple were first seen out in public at the start of the year but have been dating for some time.
'I truly tried to keep [the relationship] under wraps,' Kathy said in January, adding that they met 'at a food and wine fest - what can I say I'm a foodie.'

She later said: '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.
'For me, the thing which has become of paramount importance, is that he's really such a nice person.
'He has a really mellow temperament, which I need because I'm a spinning-out-of-control freak.'
Kathy has been married once, to Matthew Moline back in 2001, but they divorced in 2006.
