OTRC: Diane Sawyer gets musical 65th birthday surprise (Video)

Diane Sawyer appears in a promotional photo for 'ABC's World News'.

Diane Sawyer turned 65 on Wednesday but her colleagues at ABC News celebrated the occasion last week by surprising the veteran television personality in the newsroom with a rendition of the 1967 Dionne Warwick hit "I Say a Little Prayer".

She was called in and told there was breaking news and when she sat down, her co-workers burst into song, danced around and presented her with a cake. A video of the celebration was posted on the network's website, which also showed ABC News correspondents around the world participating in the fun via prerecorded segments.

Sawyer is a Kentucky native and former "America's Junior Miss" pageant winner who worked in local television news in the 1960s and served in the administration of U.S. President Richard Nixon in the 1970s. She is married to film director Mike Nichols. They have no children together.

Sawyer began working as a correspondent for CBA News in the late 1970s before moving to ABC News in the late 1980s.

She co-anchored "Good Morning America" for more than 10 years and was made anchor of ABC's "World News" evening broadcast on Dec. 21, 2009, replacing Charles Gibson, who retired, and becoming the second woman to head a major evening newscast by herself.

During her career, she has interviewed world leaders such as U.S. President Barack Obama and former presidents George W. Bush and Bill Clinton, as well as Iranian President Mahmoud Ahmadinejad. She has also had interviews with celebrities such as Mel Gibson, Whitney Houston, Michael Jackson, Madonna, Roman Polanski, Britney Spears and Meryl Streep.
