It's official: Ben Affleck and Jennifer Garner have tied the knot.

Representatives for both Affleck and Garner confirmed the marriage to The Associated Press on Thursday.

The publicists, Ken Sunshine and Nicole King, also for the first time confirmed that Garner is pregnant with her first child.

Sunshine, who represents Affleck, and King, who represents Garner, would not give any other details.

According to the National Enquirer, Garner, wearing white, sealed her union with Affleck Wednesday evening on a sandy beach on the Turks and Caicos Islands.

With the sun setting, her co-star Victor Garber reportedly watched as Garner, 33, and Affleck, 32, embraced and kissed, according to the report.

"Access Hollywood" has learned that the couple is staying at actor Bruce Willis' house on one of the islands.

Affleck and Garner co-starred in the 2003 comic book movie "Daredevil," where they played Daredevil and Elektra, respectively. They began dating in August 2004.

Garner was previously married to actor Scott Foley. The couple divorced in March 2004.

Affleck was previously engaged to singer-actress Jennifer Lopez, a relationship widely followed by the media. The couple broke it off in 2003.

Garner and Affleck's courtship, on the other hand, has been very private. The couple has only been spotted together once in public -- at a Boston Red Sox World Series game in Boston in 2004.
