Sylvester Stallone Posts Photo of Jennifer Flavin Amid Divorce Drama

Sylvester Stallone is raising some eyebrows with his latest post … dropping old photos with his estranged wife Jennifer Flavin as they go through an ugly divorce.

Sly posted the pics Monday on IG — the first one appears to be an old pic of Jennifer and him holding hands. In the second pic Sylvester, Jennifer and their 3 daughters are smiling and looking happy together as a family … it’s obvious it was taken many years ago.

He seemed to be taking a trip down memory lane … adding a simple but vague caption, “Wonderful…”

It’s interesting timing for sure … you’ll recall, Jennifer filed for divorce from Sly last month after 25 years of marriage, noting their union was “irretrievably broken.”

She also accused the actor of moving assets from marital funds …  and he’s fired back, denying that.

As we’ve reported, Sly told us he and Jennifer had just grown apart — though he acknowledged they also argued about his Rottweiler, Dwight — making it clear the marriage was dunzo and saying they wanted to work deal with everything privately.
