Tracee Ellis Ross shared a stunning photo of herself and her sister-in-law Jessica Simpson [1] via Instagram on Saturday. The Black-ish [2] star captioned the snap, "#sisters," reminding everyone just how she and the singer-turned-mogul are related: in case you forgot, Tracee's younger brother Evan married Jessica's younger sister, Ashlee [3], in August 2014, and the couple welcomed a baby girl, Jagger Snow Ross [4], just a few weeks ago. That makes Jessica Tracee's sister-in-law, as well as the daughter-in-law of Diana freaking Ross.

Before Tracee's cute social snap, she linked up with Ashlee to celebrate Evan's birthday in LA on Thursday: the outing marked Ashlee's first public outing since giving birth [5] to baby Jagger. Tracee opened up about her new family members [6] before her brother's wedding last year, saying, "We love big family stuff, and I got two more sisters now. So, it's really cool. Who knew I was going to grow up and have Ashlee and Jessica Simpson [7] as my new siblings?!" Now that you're all caught up, check out the funniest GIFs from season one of Tracee's show, Black-ish [8], as well as the cutest photos of Jessica and her own family [9].
