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."
