Beyonce's 30 Biggest Billboard Hits

Beyonce announced her pregnancy on Aug. 28 on the red carpet at the MTV Video Music Awards, hours before performing her joyful single, "Love on Top." The announcement came exactly two months after the release of "4," Beyonce's fourth solo album, which has sold 1.04 million copies, according to Nielsen SoundScan. Earlier that month, Jay-Z released "Watch The Throne," a collaborative album with Kanye West.

Following the pregnancy announcement, Beyonce released a series of music videos supporting "4," including clips for "Countdown," "Party" and "Love on Top," as well as a DVD showcasing her four performances at New York's Roseland Ballroom in August. Jay-Z and Beyonce were originally believed to be expecting their first child in February 2012, but a behind-the-scenes clip from the "Countdown" video shoot in September suggests that Beyonce was six months pregnant at the time of filming, and that the couple was expecting a December arrival.

The best-selling rapper and former Destiny's Child leader began dating in 2002, and have collaborated on hit singles like "Crazy in Love," "'03 Bonnie and Clyde" and "Deja Vu." The couple married in April 2008.
