On Saturday, Union shared three photos that show her and her former basketball star husband wearing matching paisley-print pants — and nothing else.
"Welcome to Scorpio [season]," the actress, who turns 49 on Oct. 29, captioned the post in a nod to her zodiac sign.
Wade — who turns 40 on Jan. 17, making him a Capricorn — shared the topless shoot on his own Instagram Stories, quipping, "She wanna be like me so bad."
The couple's steamy shoot was a hit with their fans and followers, who responded with a flurry of flame emojis.
"Y'all abs are offensive... I'm reporting this," sports journalist Jemele Hill joked.
"I'm trying to figure out how you still look 25! That's RUDE," responded actress Yvette Nicole Brown.
Last month Union shared footage of another topless moment, likening it to exposing her personal life in her new memoir, You Got Anything Stronger. The book sees her speaking candidly about past relationship struggles with Wade and the emotional surrogacy journey that led to the birth of their daughter Kaavia, now almost 3.
"Giving strong dancing cricket vibes but when folks ask what it feels like to be so publicly vulnerable… This right here," she said of her flashing photo. "Seriously though, if you have ever felt like you might literally die from humiliation, being vulnerable can be a challenge but lemme tell youuuuuuu, it’s actually FREEDOM. Peace & joy can live side by side with vulnerability."
