Celebrities, they’re just like us, they love hanging out with their mates and going for walks and things. However, unlike us, their mates are often famous as well. Take Katy Perry and John Mayer for example who recently went on a double date hike (so romantic) with Girls star Allison Williams and her boyfriend Ricky Van Veen.
The two couples were spotted all dressed up in their finest exercise gear walking through California and were seen laughing and joking with each other. At one point Katy was seen holding onto John's bum as they hiked through the countryside.
Katy and Allison have been spotted hanging out a lot recently, in November they headed to a Unicef ball and just a few weeks ago they were spied having a big girly natter at the Grammies where Allison took Katy as her 'date'. Allison previously said of the former Mrs Russell Brand, 'She's awesome, she's the best.'
If reports are anything to go by Katy could be in need of a new female BFF. Whilst she and Rihanna used to be like the best friends EVER it’s thought that they have been out of touch since Rihanna got back with Chris Brown last summer. Multiple reports have suggested that Katy doesn’t approve of Chris and is not keen to hang out with him.
Of course John and Katy are not the only celebrity couple to befriend another celebrity couple for the purposes of a very starry double date. Oh no. Beyonce and Jay-Z have oft been seen hanging out with Kim Kardashian and Kanye West and who can forget when the Beckham’s hung out with Katie Holmes and Tom Cruise?
