If you missed it, earlier in the day, Jessica called out Natalie for some comments she made in an interview about Jessica's bikini photo published years ago.
ET's Nischelle Turner spoke to Portman on Wednesday about her new film, Vox Lux - in which she plays a pop star - when she explained her much-talked-about quote about Simpson in an interview with USA Today. "Like, I don't know what this is trying to tell me as a woman, as a girl".
Jessica further scolds Natalie by writing, "being sexy in a bikini and being proud of my body are not synonymous with having sex". I have always embraced being a role model to all women to let them know they can look however they want, wear whatever they want and have sex with whomever they want.
Jessica Simpson has beef with Natalie Portman and between this and George H.W. Bush's funeral, the '90s are back, baby!
"I have made it my practice to not shame other women for their choices", she wrote. 'In this era of Time's Up and all the great work you have done for women, I encourage you to do the same'.
Many commenters applauded Jessica for her statement, while some argued that was Natalie calling out the magazine's portrayal of young women - not the singer.
It remains unclear what photo they were referring too, but it appears as though the singer knew exactly what image the actress meant.
"It is a mistake to say anyone's name", she says.
Mystery: It's unclear what photo they were referring to.
At the start of her career, Simpson was open about her vow to remain a virgin until marriage. There was also no reference to her being a virgin on the cover. At the time, she was dating 98 Degrees singer Nick Lachey.
Natalie has been famous since she was a child star, but she told USA Today that she thinks musicians have a harder time than actors.
"I didn't mean to shame you and I'm sorry for any hurt my words may have caused". "I felt really lucky to have her as a little kid because I saw someone who was brazen and disobedient and provocative and trying to mess with people and always changing - I thought it was a great thing to see in a woman growing up", she added.
The Oscar victor is now promoting her buzzy new musical drama, "Vox Lux", in which she plays the world's biggest pop star, beset by personal struggles.
