Los Angeles, Aug 3 (IANS): After 17 years, star couple Will Smith and Jada Pinkett Smith are reportedly ending their rocky marriage with a secret divorce deal.

"For Will and Jada, holding it together these past few years has been tough because their marriage has been on life support for a long time," a source told radaronline.com.

"They're exhausted from trying to maintain the façade of a happy union. They've decided to pull the plug in a carefully choreographed manner, (and) agree announcing their split at the end of the summer is the right move," the source added.

They have already "worked out a confidential settlement to protect their $240 million fortune, and prepare their children (son Jaden, 17, and daughter Willow, 14) for the fallout," said the source.

Hinting at their split earlier this year in an interview, the "Bad Boys" actor, 46, admitted that their marriage had "died". Meanwhile, Pinkett Smith, 43, seemed to acknowledge Will's notorious wandering eye, telling Howard Stern: "I'm not his watcher. He's a grown man."

She later added that she's fine with Will's ways, "as long as Will can look himself in the mirror and be okay."

Rumours started since 2013 that Will romanced his "Suicide Squad" co-star Margot Robbie. He's also been photographed without his wedding ring.

Pinkett Smith also allegedly cheated in 2011 with "Hawthorne" co-star Marc Anthony.

"They tried to fix things with therapy, (but) it's not happening," explained the source.

Another source said: "They're already moving on with their lives. All that's left is the inking of the divorce papers."
