Could Kim Kardashian already be pregnant with her second child? Rumors began swirling after Kardashian and her fiancé Kanye West were spotted leaving a Beverly Hills doctor's office early Sunday (Jan. 12) morning.  

According to Celebrity Dirty Laundry, the couple was photographed leaving Beverly Hills Medical Center. A source recently told Hollywood Life that Kardashian and West love being parents so much that they are eager to give their daughter North West a sibling.

"Kim finally feels like her life is exactly where she's always wanted it to be," a source told the site. "She and Kanye are already talking about having another kid because they want Nori to have lots of brothers and sisters."

The reality star hasn't addressed the baby rumors but she has been working hard to lose the baby weight. Shortly after giving birth she told her fans on Twitter that she was dropping the weight by doing the Atkins diet. In the six months since giving birth the reality star has lost a reported 56 pounds but wants to drop more.

A source told Now magazine (via the Daily Mail) that the "Keeping Up With the Kardashians" star wants to reach a size 0 and has only been eating only 1,000 calories a day.

"She's hit her goal weight but want to drop to a size 0," the source said. "She also wakes up for daily 5 a.m. workouts and often does another hour in the afternoon."

The 33-year-old has been documenting her weight loss with Instagram selfies. She uploaded a sexy bathing suit selfie showing off her curves in a one-piece swimsuit. She also uploaded a post-workout photo showing off her toned stomach with her friend Blac Chyna.

"Kim feels confident again. She worked really hard and is so motivated to stay fit," a source told US Weekly.
