Khloe Kardashian, the soon-to-be-mama, was spotted out with her sisters, Kim Kardashian and Kourtney Kardashian, for a girls' bonding in San Francisco over the weekend. Khloe, who hasn't confirmed her pregnancy yet, wowed her fans when spotted walking in the city in her high-waist blue jeans.

The "Keeping up with the Kardashian" star completed her look with her thigh-high boots, black top, and a full-length wool coat. It was one of the rare appearances that Khloe has made following her pregnancy rumors. In a report obtained by E! News last month, it was learned that the young star is expecting the arrival of her first child with boyfriend, Tristan Thompson, the Cleveland Cavaliers player.

Trip to San Francisco

While the Kardashian sisters enjoyed their trip to San Francisco, it was also reported that the girls visited Alcatraz and enjoyed a cable ride in the city.

Later on, Kim reportedly headed off to Los Angeles to join the star-studded "One Voice: Somos Live!," a benefit concert for a disaster relief telethon.

Apart from the sisters' recent bonding, Khloe was also spotted out in public earlier this month. She was seen wearing a black jacket, Louboutin heels, and a pair of leather pants, during the anniversary of her "Good American Denim Line."

In one of her interviews with People, the young star shared that her weight is fluctuating all the time but she feels comfortable with her size.

While her pregnancy news was out on different websites, Khloe and Tristan have kept mum about her pregnancy the whole time.

Wishing for kids

During the season 14 premiere of the "Keeping up with the Kardashians" last month, Khloe revealed that she and Tristan have always wanted to have their own kids. She further shared that it has always been in their plans to be together and 'grow' their own children.

Meanwhile, E! News revealed that Scott Disick opened up about Khloe during his interview. He added that if Khloe needs advice on raising her child, Disick would be willing to give it. As he concluded his statement, Disick added, "I don't really need to give advice per se because we are right there. It's not like long-distance, 'hey, maybe you should try this?"

Khloe's happy news

Khloe's pregnancy news came shortly after r sister, Kylie Jenner, made headlines with reports that she's also pregnant with her first child. In a report by US Magazine, the Kardashian-Jenner siblings are due in early 2018, which is also the exact time that Kim and Kanye West will welcome their third child from a surrogate parent.
