Jennifer Lopez looks good in a bikini, but it has been five months since Lopez gave birth to her twins and although she initially shed much of the 50 pounds she had gained while pregnant, she is now hit a roadblock on losing the rest.

Recently, Lopez hit the beach in a bikini and the extra 20 pounds she is still carrying were plainly visible, especially on her stomach and thighs. But who cares, right? Well, reportedly Lopez does care. “She gets so frustrated,” says one insider. “She says, ‘I just hate having these extra pounds! I want to look like my old self.’”

According to another source, “Jennifer thinks her thighs look terrible. She has major cellulite. She thinks her face and body look totally different than they did before she was pregnant. She believes she’s lost her figure forever, and she’s desperate to get it back.”

Dangerous diet tricks Jennifer is so determined to shed the last 20 pounds of baby fat, she will consider anything. She even thought about lipo, says a source, but then decided against it.

Instead, she reportedly has been trying other drastic methods, which could have dangerous side effects. Allegedly, Lopez often sits in a sauna for up to three hours a day. “She just sweats the weight away,” says the source. “It works to lose a few pounds, but it’s all liquid, Jennifer has also tried fasting. She will go for days without eating, says a source, or eat only oranges and Saltine crackers. But it leaves her with no energy.

Personally, I doubt that much of what those sources are saying is actually true. Lopez looks pretty good in a bikini, considering that she has recently given birth to twins. She needs more time to get in shape, but I am pretty sure she will get there sooner than we expect. [source: Star]
