Kevin Jonas says his marriage will be no barrier

Kevin Jonas isn't worried his marriage will split the Jonas Brothers apart.

The 22-year-old star – who tied the knot with long-term love Danielle Deleasa last December – has been joined on the trio's current US tour by his spouse and even though they travel on a separate bus to his brothers Joe, 21, and 17-year-old Nick, he insists the new addition to their entourage doesn't cause any problems.

Kevin told USA Today newspaper: "Adding a new element to a rock band is always risky.

"But with Danielle, it's been all good. And the brothers still find time to hang out, just the three of us, too.

"We spent the first two nights of the tour on Joe and Nick's bus, and that was fun. They joke around with her all the time, just like she's their sister."

The newlyweds have also started to make their own bus as homely as possible, adding rugs and putting up pictures to remind them of home.

Kevin added: "We have this method, where we use different suitcases that hold the clothes and things you'll need for different days.

"We're also putting up family photos. We went shopping at Target to get some new rugs, and we have great food in the fridge."

Danielle, 23, also added she is adapting to life on the road and is glad she gets to spend every day with her new husband.

She said: "I brought my pillows from home. The hardest thing is packing, especially for a girl. But Kevin's such a pro at touring, he made the transition easy for me.

"And I get to be with him all the time."
