Jennifer Lopez is grateful to have Casper Smart on her world tour.

The 'On The Floor' hitmaker is thankful to have the support of her dancer boyfriend, who has a central part in her 'Dance Again' concerts, because being away from home for so long is hard and she knows he always has her best interests at heart.

She said: ''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.''

Casper added: ''Going out on a project like this, you need all the love and support you can get.''

Jennifer is also joined on tour by her mother Guadalupe, who helps keep her four-year-old twins Max and Emme - whose father is the 43-year-old star's ex-husband Marc Anthony - up-to-date with their education.

Jennifer explained to 'Entertainment Tonight': ''They have their little school, my mom was a teacher for 20 years so she came on the road with me to tutor them.''

Casper, 25, also revealed one of his most memorable moments with Jennifer - who he has been dating for around a year - was Valentine's Day (14.02.12).

He recalled: Valentine's Day was a big thing. I rented a helicopter and we went to Laguna Beach. I did a big thing out there.''
