Naomi perhaps had an extra reason to smile – she is reportedly preparing to tie the knot with her partner of nine years, Liev Schreiber.

The couple have been in a relationship since 2005, and are parents to two sons, six-year-old Sasha, and five-year-old Samuel.
"Naomi and Liev are more in love than they've ever been and are definitely serious about getting married," a friend of the couple told RadarOnline. "It's a big step after all this time, but they're ready to marry."

The insider said that while the couple have had "their ups and downs, including a cancelled New Year's Eve wedding right before 2008, they've finally worked out their differences and are rethinking marriage," adding, "Liev fell in love with Naomi all over again this past year."
The long-term couple reportedly grew closer after Naomi faced criticism for her latest film, Diana.
"Liev really admired how Naomi rose above the flak she got for Diana – a role he really thought she'd win awards for," the friend revealed.

"She was totally heartbroken over that movie and Liev has played a huge role in getting her confidence back so she could carry on with four more films she has in production."
In the past, the couple have said they are very much together, regardless of whether they marry.
"We just don't have that certificate and that's ok with both of us," Naomi said in a 2012 interview. "Maybe one day we'll wake up and go, 'Hey, let's do this.' And maybe not."
