I am grateful to have Casper Smart: Jennifer Lopez

London: Singer-actress Jennifer Lopez is grateful to have her boyfriend Casper Smart on her world tour because she needs his support.

The `On The Floor` hitmaker says her dancer boyfriend, who has a central part in her `Dance Again` concerts, always has her best interests at heart, reported Showbizspy.

"You want people around you who genuinely care about you, not people that are just there for a paycheque. Obviously he does care so... It`s been great to have him there on the road," Lopez said.

Lopez, 43, is also joined on tour by her mother Guadalupe, who helps keep her four-year-old twins Max and Emme up-to-date with their education.
