Kim Kardashian gave birth to daughter North West 13 months ago, and she's very eager to give her adorable little girl a sibling -- and STAT!

A source tells close to the reality TV starlet tells Us Weekly that Kim and hubby Kanye West "tried to get the ball rolling while on their honeymoon in early June" in Mexico. Um, one would hope that they were enjoying some quality naked time on their romantic retreat! Ok, now we need to get that image out of our minds...

The mag reports that West and Kardashian returned to Punta Mita earlier this month in the hopes of trying again while the rapper records his new album, but Life & Style claims that she's already got a bun in the oven! “The amount she has been eating recently has people sure she’s pregnant again,” a family friend told the mag. “She’s usually careful about what she eats. … Kim has gained weight and she knows it.” A source added to L&S, “If it was up to him, Kim would have had a baby right after Nori ... He has been all about Kim getting pregnant.”

And after the criticism Kardashian was hit with during her first pregnancy, Us mag says she wants to keep this under wraps as long as possible. “Kim won’t tell anyone until she’s five months along,” a source told the mag. “She doesn’t want people scrutinizing her body.”
