Jessica Simpson Likes Jeremy Renner's Workout Video on Instagram 15 Years After Rumored Romance

What's going on between Jessica Simpson and Jeremy Renner?

About 15 years after the two stars sparked romance rumors, Simpson pressed the like button and left comments on two of Renner's recent workout videos — and the Mayor of Kingstown actor returned the favor.

Renner, 54, shared a video of himself working out solo, both fully clothed and shirtless, to Instagram alongside a caption about finding "inspiration everywhere, especially when I need it most." Simpson, 44, liked the post and commented a fire emoji.

The "With You" singer also liked Renner's March 24 post of a workout video with his mom, writing in the comments section, "I love this oh my...Mama is STRONG...I need to go do sit ups now."

The Avengers: Endgame star has also been paying attention to Simpson's Instagram, as he liked her two latest posts promoting her new Nashville Canyon, Part 1 project.

Underneath her March 21 post about the new music, Renner commented, "Congrats Jess !!! 👏👏👏🔥" He also liked a March 25 post about her new song "Blame Me."

The interactions come more than a decade and a half after sources told PEOPLE the pair "were really flirting up a storm" at a cocktail party in Los Angeles to celebrate Renner's role in The Hurt Locker.

At the time, PEOPLE reported they exchanged numbers at the event.

Nashville Canyon, Part 1 not only marks Simpson's first new musical project since 2010, but the songs arrive after she announced her separation from Eric Johnson after 10 years of marriage in January 2024. The two share daughters Maxwell “Maxi” Drew, 12, and Birdie Mae, 6, and son Ace Knute, 11.

"Eric and I have been living separately navigating a painful situation in our marriage," said Simpson in a statement to PEOPLE at the time. "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."

During a recent performance at Willie Nelson's Luck Reunion festival in Texas, per fan-captured TikTok footage, she got candid about the separation.

“I was out in Nashville and I had my heart wide open, I was in a very intuitive state and I had to ask some very personal questions on the home front,” Simpson told the crowd. “And I found out that my world had been turned upside down and that life was now very different."

"I am a very single lady," added the "Leave" musician.
