No mean feet: Russell Brand and Katy Perry take a walk in Griffith Park, Los Angeles before embarking on a hike up to the observatorySo, you're hiking up a rocky embankment in the U.S. - what do you decide to wear on your feet?
For the average person a pair of hiking boots or similarly thick-soled footwear would suffice, however Russell Brand and his fiancee Katy Perry went for a somewhat impractical choice for their rocky adventure - flip-flops.
The couple took a trip to Griffith Park in Los Angeles, where they hiked up to the park's observatory.

Griffith Park Observatory opened in 1935, but it was closed for renovation in 2002.
It reopened in 2006 after a $93million facelift and continues to be a popular destination for LA residents and visitors alike because of the stunning views it offers and the serenity of its surroundings.

Away from work Katy is busy planning her wedding to British comedian Brand.
