Los Angeles, Sep 12 (IANS): Actress Naomi Watts and actor Liev Schreiber's children are putting pressure on them to get married.

The couple of nine years, who has two sons - seven-year-old Sasha and five-year-old Samuel - never had marriage on their priority list. But their sons are keen to see their parents walk down the aisle and have started helping them tentatively plan their wedding, reports contactmusic.com.

A source told US OK! Magazine: "Marriage was never a big deal to Naomi or Liev. But now their boys are asking whey they aren't married, so they're gonna take the plunge."

"They would do anything for their kids, and they think it will be a fun family thing to plan together,” the source added.

If the two go ahead and get married than they would want the ceremony to be a small affair for just close friends and family.

"It will be a small, intimate wedding, with just immediate family and friends. Their sons will be the only members of the wedding party,” said the source.
