Is There Trouble In Jessica Simpson's Marriage?

On Sunday, Tracee Ellis Ross took to Instagram to post a photo of herself with the singer as they sit on a staircase and show off their photogenic features. In the caption, Ross wrote, "#sisters," which is sort of accurate.

Ross's younger brother is Evan Ross, who is married to Simpson's younger sister Ashlee. Tracee is the sister-in-law of Ashlee, so in a way, Tracee and Jessica are in-laws too.

Jessica Simpson Flaunts Bikini Bod On Instagram

Jessica is 35-years-old now and looking just as dashing as she looked in 2005. in the snapshot, she wears a tight black dress showing off her long legs. With her wavy hair flowing down, Jessica still knows how to be presentable for the camera.

The blonde beauty has been married to Eric Johnson for the past year. They have two children together, Maxwell, 3, and Ace, 2.

Jessica made headlines earlier this year in an interview with Extra where her mannerisms were odd to say the least. As she opened up about her daughter, Maxwell, her facial expressions and speech patterns didn't seem too put together. But she did manage to get the words out on how she loves spending time with her kids.

"My kids are absolutely my priority," she said via Daily Mail. "My family is everything to me."
