Make-up free Katy Perry lets it all hang out in micro shorts and vest top as John Mayer snaps a photo during Hawaii vacation



It was an unconventional way to ring in the New Year, but since when has Katy Perry been known to be conventional?



The 28-year-old singer joined John Mayer for a muddy offroad tour in Hawaii on January 1.



Katy was seen running and laughing as the couple trekked through the mud in unusual attire.

The I Kissed a Girl hitmaker staggered back from her kitschy costumes for a kick around outfit that could stand to get dirty.



And it appeared she had reached to the very back of her closet for a tribal print shorts and tank top set, which she paired with no-lace black canvas sneakers.

Katy and John rode a two-seater ATV through a muddy trek on the island of Kauai, trailed by several other tourists.



And when it came time to stop, she dropped her orange cloth face mash and proudly revealed her make-up free face.

Taking a break: The couple had a brief chat while they waited by their car Not her best look: Katy wore an odd shorts and tank top combination with a pair of black canvas sneakers and black bikini bottoms Katy's raven hair was swept back off her face and she laughed with John, who took pictures of her posing on a dirt road, surrounded by shrubs.

The couple have been dating for several months now, and also spent Christmas together.

Reports suggest John spent the holidays with Katy's family at their home in Santa Barbara.

The pair decided to share some goodwill during their stay, stopping in at a local hospital on behalf of the Dream Foundation on Saturday.

The organisation helps to grant wishes for adults battling life-threatening illness.

And they're off! John drove away with Katy in the passenger seat After their visit, the Dream Foundation tweeted: 'Gratitude to @KatyPerry @JohnMayer & Hudsons for rolling up their sleeves & serving our dream families. #DreamTeam.'

While it won't be the first time John, 35, has met Katy's family, the decision to spend the festive season with the Perrys marks a serious step in the couple's romance.

A source told People.com : 'They're happy together and with her family for the holidays. John really likes getting to know Katy's family better. 'They've spent a lot of time together and really enjoy each other's company. John is entirely focused on Katy.'

It was also recently reported that John has designed a guitar to give to Katy as her Christmas present.
