The 'Cake' actress, who married the 'Leftovers' star in August, has reportedly never been happier and loves life with her "adventurous" new husband.

A source close to the 46-year-old star said: "She says their sex life is off the charts, and Justin is very adventurous. Their new thing is eating dinner in the nude! Jen says marriage seems to have made Justin even more passionate."

While the couple are madly in love, they try not to spend more than four hours together every day in a bid to keep their spark alive.

The insider told US OK! magazine: "There's no doubt they love each other and really are best friends, but they are careful not to spend too much time together. They just enjoy their own space too much.

"They flirt by text and love to send each other pictures of their wedding rings."

The 44-year-old actor and screenwriter has been working in Texas for new movie 'Zoolander 2' and recently admitted he loves being married to the former 'Friends' star.

He said: "It's fantastic. Something really does shift in a wonderful way and it refocuses things and in a weird way, it was a long time coming."
