Simpson last appeared on Billboard's charts in 2008.

Ashlee Simpson and Evan Ross make their Billboard chart entrance as a duo, as the couple's new single "I Do" enters the Pop Digital Song Sales chart at No. 6 and the all-genre Digital Song Sales chart at No. 16.

The track sold 11,000 downloads in the tracking week ending Sept. 13, according to Nielsen Music.

Billed as Ashlee + Evan, the duo released "I Do" on Sept. 7, two days before the premiere of their new E! reality show Ashlee + Evan. A collaborative album by the pair is also reportedly in the works, along with solo sets by each singer.

While "I Do" earns Ross his first entry on a Billboard survey, Simpson scores her first chart placement in 10 years. She last appeared with "Little Miss Obsessive," with Tom Higgenson, in 2008; the song reached No. 26 on Dance Club Songs and No. 96 on the Billboard Hot 100.

Simpson has made seven trips to the Hot 100, beginning with her biggest hit, "Pieces of Me," in 2004:

Title, Peak Position, Peak Date
"Pieces of Me," No. 5, Sept. 18, 2004
"Shadow," No. 57, Oct. 30, 2004
"La La," No. 86, Feb. 26, 2005
"Boyfriend," No. 19, Nov. 5, 2005
"L.O.V.E.," No. 22, Feb. 4, 2006
"Invisible," No. 21, Aug. 12, 2006
"Little Miss Obsessive," with Tom Higgenson, No. 96, May 10, 2008

All three of Simpson's studio albums landed in the top five of the Billboard 200 chart. 2004's Autobiography and 2005's I Am Me both bowed at No. 1, while 2008's Bittersweet World reached No. 4. Simpson was then starring in MTV's The Ashlee Simpson Show, a spinoff of older sister Jessica Simpson's Newlyweds: Nick and Jessica, also starring Nick Lachey.
