JUSTIN & JESSICA SEPARATE LIVES

It's been months since Justin Timberlake and Jessica Biel were last spotted together in public!

On Mother's Day, Justin Timberlake shared a gushing Instagram post about wife Jessica Biel, calling her a "brilliant, beautiful, bada--." He went on to write that the Sinner star, 41, was "always there" for him and their two young sons - Silas, 8, and Phineas, 2"no matter the time of day or night."

While it's a lovely sentiment, an insider reveals that Jessica and Justin, 42, are actually rarely in the same place at the same time these days. In fact, after photos emerged of the singer alone in NYC between May 23 and May 28, the actress attended the LA premiere of Cruel Summer, which she executive-produces, solo on May 31. The last time the duo were pictured alongside each other in public? At an October fundraiser for Children's Hospital of Los Angeles.

"They live separate lives," confirms an insider. "They're with each other less and less, yet continue to post about their love for one another online. Justin and Jessica are kind of a hard couple to understand."
