I am grateful to have Casper: Jennifer Lopez

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.
