MStars News previously reported that Simmons's eldest daughter Ming Lee Simmons announced that she was going to get another little brother via Instagram. Now we've seen some of this weekend's celebrations as Kimora and her family hosted a baby shower in honor of the new bundle of joy expected to be welcomed into the world this spring in April.

According to snapshots seen below, Kimora's first husband Russell Simmons attended the shower, including Eddie Murphy's ex-wife Nicole Murphy and Gabrielle Union.
