When it comes to her boyfriend Casper Smart, Jennifer Lopez gets the royal treatment.
“He treats her like a queen,” a source tells PEOPLE in this week’s issue. “Casper centers everything on Jennifer.
Dating six months, the fast-moving couple – Smart moved into the Hidden Hills, Calif., mansion that Lopez shares with her 4-year-old twins Max and Emme at the start of the year – haven’t let their 17-year age gap slow them down. (She’s 42; he’s 25.)
Still, some friends wish that the wedding-loving superstar – who split from singer Marc Anthony last summer – would take things slowly for a change.
A Lopez family source says some members of her inner circle “worry that Casper will take advantage of her. She has fallen so hard.”
But the American Idol judge, who recently announced her plans for a summer tour that Smart will help choreograph, seems just fine with her reputation as a commitment-happy kind of woman.
At a recent press conference for her upcoming film What to Expect When You’re Expecting, she laughingly summed up her view on love: “I’m a bit of a romantic, if you hadn’t noticed.”
And soon everyone will be able to watch the couple’s chemistry: Lopez and Casper are scheduled to perform a sexy single together on American Idol Thursday night.
