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.

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.

After their visit, the Dream Foundation tweeted: 'Gratitude to @KatyPerry @JohnMayer & Hudsons for rolling up the! ir sleeve! s & 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.

Apparently, the instrument is covered in intricate designs, including Katy's initials and the date they first met.

A source told The Sun newspaper: 'John has put some serious effort into his Christmas gift for Katy."Since they met he has been trying to prove he isn't the guy everyone says he is.

'This should definitely prove that - every little detail on the guitar shows how much he thinks of her.'

Katy has been dating John on and off following her divor! ce from c! omedian Russell Brand in July.

Since her split, she's been linked to a number of men, including Florence And The Machine guitarist Rob Ackroyd and model Baptiste Giabiconi.

John also has a notorious reputation for loving and leaving some of Hollywood's most eligible ladies, including Taylor Swift, Jessica Simpson, Jennifer Aniston, and Jennifer Love-Hewitt.
