Kim Kardashian oozed sex appeal during a date night with boyfriend Kanye West on Friday night as they left their daughter North West at home. Wearing a skintight, long-sleeve gray dress, Kardashian showed she has bounced back after giving birth in June. West, who is usually quite private, appeared excited to show off his beautiful girlfriend as they posed for pictures for the paparazzi.

The two were headed to the Los Angeles Opera in downtown L.A., and Kardashian accessorized her stunning dress with tan heels, a small black clutch and a necklace that read “Nori,” North’s nickname. Meanwhile, West was more casually dressed in a white button-up shirt, ripped blue jeans, and black loafers.

It is clear Kardashian has come back to the spotlight hotter than ever, as she has begun showing off her slimmed-down post-baby body. She may even be preparing for another photo shoot in Playboy, after having had her first cover in 2007. On an episode of “Keeping Up with the Kardashians” that was shown recently, she said she wanted to do another nude shoot.

By the looks of it, she is certainly on the right track, although it’s unclear how much more weight she has to lose. Kardashian has been working with celebrity trainer Tracy Anderson, who has whipped stars including Gwyneth Paltrow and Nicole Richie into shape.

“She’s a gorgeous woman. I think the reason why the weight is coming off is because she’s very connected. I went and met little North, and Kim’s really taking it in stride,” Anderson recently told E Online. “She’s really connected to the baby, which is what’s important. She’s focused on the baby and nursing and taking her time.”
