Jessica Simpson perplexed fans with a rare photo her mother, Tina.

The “With You” singer posted a heartfelt tribute to her mom via Instagram in honor of her 65th birthday Saturday, however fans were left scratching their heads by Tina’s unrecognizable appearance.

“Is your mom in the room with us? Who is this?” one user commented, while another echoed, “Who is that? Does not look like her mom.”

Yet another fan wrote, “Omg that looks nothing like Tina,” while another confessed that they thought Tina was actually her younger daughter, Ashlee Simpson.

“Huh? Is her mom taking the picture?” another netizen wondered.

Jessica, 44, gushed over her mom in her lengthy birthday message, which did not include any mention of the matriarch’s seemingly changed appearance.

“I love to love you, make you proud, hug you and work alongside you each and every day for eternity!” the “Take My Breath Away” songstress wrote in part.

“Thank you for making me a priority and for always giving me the no matter what kind of love!”

Tina replied to her firstborn daughter with a loving comment.

“I love you Jessica thx you for such a beautiful tribute I am so grateful for my family and friends,” she wrote. “Thank you all for the beautiful birthday wishes! I Love You All 🙏🏼🥳❤️ This is 65 Hello Senior Discounts! 🙌 🙌🙌.”

The “Dukes of Hazzard” star has made headlines recently after confirming her split from husband Eric Johnson after 10 years of marriage.

Simpson and the retired NFL player, 45, share three children: Maxwell, 12, Ace, 11, and Birdie, 5.

“Eric and I have been living separately navigating a painful situation in our marriage,” Simpson said in a statement to People last Monday.

“Our children come first, and we are focusing on what is best for them. We are grateful for all of the love and support that has been coming our way, and appreciate privacy right now as we work through this as a family.”

A family source exclusively told Page Six that the fashion mogul’s 100-pound weight loss contributed to the demise of their marriage.

According to the insider, Simpson’s confidence in her body “unleashed a whole new side of her personality. She suddenly felt 21 again.”
