London - 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 pay cheque. 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."
