In a hilarious Instagram post on Nov. 19, the actress, 36, shared some self-deprecating comments alongside a split image of J.Lo, 47, and herself wearing the exact same designer dress.
"I tried this dress on the other day and then saw @jlo wearing it in a magazine and thought "Oh, THAT'S what it's supposed to look like." 😝😂," Olivia captioned the pic.
J.Lo had donned the dress for a Mark Seliger photoshoot that appears in the newest issue of Harper's Bazaar.
ETOnline reports that the dress is by Bailmain and retails for $16,830.
The "On the Floor" singer paired it with a black and green belt and strappy Giuseppe for Jennifer Lopez stilettos. The particular pair she's wearing -- aptly named the "Jen" -- are one of six styles that will be released in January, according to an Instagram post shared by the shoe brand.
We can't wait to see what Olivia ends up wearing to the American Music Awards on Nov. 20 when she takes the stage to present.
Sadly, Jennifer won't be at the AMAs this year.
