Jennifer Lopez is taking her children on tour.

The 42-year-old star - who has four-year-old twins Max and Emme with estranged husband Marc Anthony - admits she is nervous about being with youngsters while she plays gigs around the world but thinks it will be a ''learning experience''.

She said: ''We're going on tour in the summer and they won't be in school that time, so they'll be coming with mummy.

''I don't know how it'll work because this is my first time. They'll be on the bus with me, so it will be a learning experience for all of us.

''I guess they can go to grandmother's house for a few days if they get tired and crazy. I'll get it out as soon as I go, but I can't be away from them for too long.''

Jennifer, who is now dating 25-year-old dancer Casper Smart, admits she wants her kids to be grounded when they grow up, even though they are comfortable surrounded by her showbiz lifestyle.

She added in an interview with Britain's OK! magazine: ''It's funny, they know a little bit of what I do and they get it.

''They know I dance, they know I go in hair and make-up and I go and do things. When we go out we get bombarded, so I've learned to move in those circles really well.

''I don't want them to get overwhelmed by people. They seem very happy and loving and perfect.''
