Oscar-winning Hollywood heart-throb Ben Affleck and his girlfriend of nine months, Jennifer Garner, are engaged to be married, according to People magazine.

Affleck, 32, popped the question at the weekend, the weekly celebrity publication said, setting the stage for a second round of "Bennifer" wedding fever following Affleck's aborted nuptial plans with Jennifer Lopez.

"Though neither Affleck nor Garner will officially confirm it, a close friend of his has been spreading the word that the couple are going to tie the knot," the magazine said.

Affleck's publicist has denied the pair are planning to marry, while Garner's representatives refused to comment on the rampant reports of the pair's betrothal.

But Star magazine reported that Pearl Harbor star Affleck went down on one knee during a party at the weekend to celebrate the 33rd birthday of Elektra actress Garner at her Los Angeles home.

The couple, who met during the filming of comic book adventure Daredevil began dating in August 2004, after the official break-up of the last relationship dubbed "Bennifer" by the press in January that year.

Affleck and Lopez split four months after the abrupt cancellation of their very high-profile wedding that was announced following a whirlwind romance sparked when the couple met on a movie set.
