Miley Cyrus this week becomes the second-youngest artist ever to have two albums topping the Billboard chart.

The 15-year old Disney superstar tops the chart this week with her sophomore album Breakout. It was released under Hollywood Records on July 22, 2008 and in just a week it has sold a whopping 371,000 copies to place on the no. 1 spot. Last year, Miley hit no. 1 when her Hannah Montana two-CD set album sold 326,000 on its first week.

Cyrus is only the fifth performer to land two #1 albums as a teenager. She follows LeAnn Rimes, who was also 15 when she landed her second #1 album; Hilary Duff and Joey McIntyre from New Kids on the Block, who were both 17; and Britney Spears, who was 18.

To break the tie between Rimes and Cyrus for the youngest artist with 2 no. 1 albums, Rimes was 7 months younger when she landed her second #1 album.

On the other hand, Stevie Wonder still holds the record for the youngest artist with a #1 album. He was just 13 and three months in 1963 when he topped the chart with Little Stevie Wonder – The 12 Year Old Genius.

Other teen stars whose albums hit #1 are Tiffany (who was 16 when she topped the chart in 1988), Bobby Brown (19 when he scored in 1989), Debbie Gibson (18 in 1989), the rap duo Kris Kross (13 and 14 in 1992), Christina Aguilera (18 in 1999), Avril Lavigne (19 in 2004) and Ashlee Simpson (19 in 2004).

Miley has 10 songs on this week’s top 200 Hot Digital Songs chart, the most anyone has had in one week since David Cook put 17 songs on the chart in the week following his American Idol victory. All but two of the 12 songs on Cyrus’ album are listed on the download chart. Her highest-ranking song is “7 Things,” which dips a notch to #4.

Another interesting fact about Miley’s feat was her father Billy Ray Cyrus logged 17 weeks at #1 in 1992 with his debut album – Some Gave All. The Cyruses are one of only two families in which both a parent and a child have had #1 albums. The other father-and-daughter team are The Coles. Nat “King” Cole hit #1 in 1957 with Love Is The Thing. Daughter Natalie Cole reached the top spot in 1991 with her tribute to her dad, Unforgettable With Love.
