There was a modern family gathering when Jennifer Lopez joined her ex-husband Marc Anthony to celebrate his son Cristian's 12th birthday, from his marriage to Dayanara Torres. Also at the house party were J Lo's boyfriend Casper Smart, and Marc's ex-girlfriend Shannon De Lima . The family looked delighted to be sharing the celebrations. "Happy Birthday Cristian!!! #houseparty #FAMILIA." J Lo wrote on Twitter. The On the Floor singer embodied casual chic as she wore a white t-shirt with a gold logo, had her hair tied up in a bun and wore bright red lipstick.
Although Cristian's mother Dayanara, who had an on-off four-year relationship with Marc, did not take part in the reunion, she tweeted a picture of a big birthday cake and added: "My Christian just turned 12! Time does fly, can't believe it. So proud of him, my sweet boy."J Lo and Marc Anthony announced the "difficult decision" to end their seven-year marriage in July 2011. The couple, who have four-year-old twins Max and Emme, have been determined to remain friends. "He will always be in our lives," says J Lo. "He will always hold a special place in my heart as the father of my children.
"You know, we respect each other," she says. Last year, the couple worked together on Q'Viva! (The Chosen), a reality TV show which searched for the best singers and dancers in Latin America. "We're just meant to be in each other's lives in different levels," says Marc. Marc, 44, was married to Dayanara Torres from 2000 to 2004. They had a rocky relationship, separating in summer 2002, but they later reconciled and renewed their vows in a lavish ceremony in Puerto Rico in December 2002. They have children Cristian, 12 and Ryan, 9. J Lo, 43, has had previous high-profile relationships with Ben Affleck and P.Diddy. "Sometimes it doesn't work and that's sad, but I remain an eternal optimist about love," she has said. There is an 18-year age gap between J.Lo and her current boyfriend, 25-year-old dancer and choreographer Casper Smart. J Lo admits that she thinks about the age difference. "The truth is we don't know what's going to happen," she says. "We're loving this moment right now. We make each other happy."
