Jessica Simpson, Tracee Ellis Ross 'sisters' photo posted to Instagram

In case you missed it, Jessica Simpson and Tracee Ellis Ross are sisters. The Black-ish star posed with her sister-in-law for a glamorous pic posted to Instagram, reminding us all that these two lovely ladies are part of one big, talented family.

Tracee captioned the above photo with the hashtag “#sisters.” Her younger brother Evan married Jessica’s sister Ashlee back in August 2014. Evan posted photos from the ceremony in Greenwich, Connecticut about a month ago and expressed his excitement to welcome their baby girl into the world.

Ashlee recently gave birth to their first child a few weeks ago. In an Instagram post, the singer wrote, “We are overjoyed about the birth of our precious baby girl Jagger Snow Ross.”

As an added bonus, all of this means that Jessica and Tracee are related through marriage. The pair recently connected for Evan’s birthday this past Thursday, which also marked Ashlee’s first public appearance since the birth of Jagger.
