RYAN Reynolds and Sandra Bullock have reunited to wish former co-star Betty White a happy birthday.

The trio starred alongside each other in rom-com classic The Proposal.

Former Golden Girls star Betty turned 98 today, with the Hollywood stars marking the momentous occasion with a funny video online.

In the video, which was shared to Twitter, Ryan and Sandra battle it out for Betty's attentions while singing happy birthday.

The pair sang their parts of the song separately to the camera.

As the tune came to an end, Sandra jokes: "From Sandy, who loves you more than Ryan."

The video then cuts to Ryan, who says: "From Ryan, who loves you SO much more than Sandy."

The actor then showed off his witty personality, saying: "What did Sandy ever do for you every year?

"Did she ever show up and hand-deliver flowers to you wearing nothing but black socks and a dozen gold bracelets just like you requested? Doubt it."

Alongside the post, Ryan wrote: "Happy 98th Birthday to the one and only Betty White #XCVIII @BettyMWhite".

The 2009 movie sees Sandra take on the role of a Canadian executive, who forces her assistant Andrew (Ryan) to marry her to avoid deportation.

Meanwhile, Betty stars as Andrew’s grandmother Annie.

The comedy star celebrated her 97th birthday playing poker with her friends, according to TMZ.

Betty is best known for playing the lovable Rose on The Golden Girls, which ran from 1985 to 1992.
