Ciara was seen filming a cameo appearance for Keeping Up With The Kardashians alongside Kim at the upmarket Bel Bambini boutique on Robertson Boulevard in Los Angeles on Wednesday (12 February).
Was Ciara getting some tips on maternity fashion from mum-of-one Kim?
We certainly don't think she needs any! Ever since Ciara announced her first pregnancy in January, the beautiful singer has looked nothing but immaculate in an array of gorgeous outfits that flatter her growing baby bump.
Yesterday was no different as the 28-year-old chose a comfortable, loose fitting white shirt dress and gladiator-style sandals for her shopping spree.
Ahead of her trip to Bel Bambini, the star posted a pretty selfie to Instagram showing her baby bump from a side angle.
Ciara added the caption: "Me Before Going 2 Do Some Baby Prep Stuff With My Friend Kimmie. #ExcitingTimes.. Still Feels Surreal That This Is Actually Happening. Xo. Mommy @kimkardashian. #PerfectDay."
She's expecting her first child with producer/musician fiancé Future later this year.
Kim, meanwhile, is no stranger to maternity fashions as she gave birth to her first child, daughter North West, in June 2013.
Yesterday, the reality star was without little North for her day out but certainly turned heads in a skintight leather Givenchy skirt, Tamara Mellon Legging Boots and a figure-hgging white Lanvin top. She really does love her skintight clothing, doesn't she?!
Ciara and Kim have been close friends for a long time. In fact, back in 2010 Kim actually wrote a blog post complimenting Ciara's fashion sense and pointing out how similar the two women are when it comes to taste.
"One of my best girl friends Ciara was over yesterday and we were going through my closet and comparing clothes," wrote Kim at the time. "We literally have the same taste in fashion so we're always buying similar pieces. I think that happens when you're really close with your girl friends."
Kim added: "People are saying she's copying my look, but it's really not like that at all, lol. We have really similar fashion sense so we're always talking about outfits and looks we love."
Aside from sharing tips on babies and fashion, the two women have surely been chatting all things wedding as both became engaged last year – in the same month!
Brunette Kim accepted a proposal from rapper Kanye West on her 33rd birthday in October, while the same month Future popped the question to Ciara in New York while celebrating her birthday!
