Naomi Watts and Liev Schreiber wedding plans are underway as "X-Men's" Sabretooth and the "Diana" star are reportedly thinking about taking their relationship to another level after nine years together.

This isn't actually the first time the couple was reported to be getting hitched. In 2007, a Naomi Watts and Liev Schreiber wedding was set on New Year's Even before 2008 but it was cancelled at the last minute.

There was also the report by Star magazine of how Liev Schreiber was jealous of his partner's friendship with Simon Baker of "The Mentalist."

But a source told Radar Online that Liev Schreiber "fell in love with Naomi all over again this past year," and that "they are ready to marry.

If ever the Naomi Watts and Liev Schreiber wedding will push though, they have the film "Diana" to thank for. According to the website, the "21 Grams" actress took it hard when the Princess Diana biopic flopped at the box-office and was panned by critics.

That's when her partner of nine years saw how strong the Australian actress was, with a lot of support from him, especially since she thought it was a film where her acting will be recognized by award-giving bodies.

The couple is both parents to two boys, Alexander and Samuel, ages 6 and 5, respectively, said news.com.au. They are not thinking about having another kid, unless they are absolutely sure they will have a girl.

Both Naomi Watts and Liev Schreiber were introduced in 2005 at the Met Costume Institute Gala in New York.

The Aussie actress recalled that it was her who pursued another date by asking him if he wants her number. And while she opened up earlier about the possibility of a Naomi Watts and Liev Schreiber wedding, the "X-Men" star was tight-lipped saying that their relationship is private.
