The 44-year-old actress has been attaching a sliver of snakeskin to her toenails and painting over it with a clear sealant, reported Showbiz spy.
"It sounds gross, but it really does look amazing. Jen first heard about the toenail touch-up from buddy Chelsea Handler, who had it done in Las Vegas.
"It's a strange process, but Jen's absolutely thrilled with the results � perfect toenails. Jen wouldn't use the real deal because (her fiance) Justin Theroux wouldn't approve. He's been a strict vegetarian for years. And they love animals. In fact, they recently adopted a pup together," a source said.
