Jennifer Lopez's fabled perfectionism reportedly extends to her new role as a parent.
The singer – who gave birth to twins Max and Emme in February – is said feel she's failing in her quest to be the “perfect mother” to her two girls.
"Jennifer wants to be the perfect mother, but she crumbles if any normal little thing goes wrong,” says a source.
"If the twins cry, she thinks it's because she's a bad mom, and bursts into tears herself.
"Marc had to sit her down and make her understand that she's a good mom and it's normal for babies to cry."
And husband Marc Anthony is worried that this self-imposed pressure – combined with her efforts to ditch the 50lbs she gained while pregnant - is taking its toll on her health.
The source tells Closer, "Jen is a total perfectionist, and she's treating motherhood the same way she goes about her career -- it's all or nothing.
"Marc is concerned that she's not eating properly or sleeping because she's obsessed with looking after the twins. If she leaves them with her own mother for a couple of hours to have some time off, she beats herself up about it and feels guilty.
"Marc has forced Jen to take some time off and have a massage to unwind, but she even struggled to relax during that.
"He wants her to stop worrying abut the kind of mother she's being and just enjoy it."
