Selena Gomez just might have a post-birthday celebration to plan next week.
The singer, who turned 21 on July 22, is projected to top the Billboard 200 chart for the first time with her new album, "Stars Dance."
The album, which was released on July 23, is expected to sell anywhere between 90,000 and 100,000 copies in its first week, Billboard reports.
Gomez's last album, "When the Sun Goes Down," debuted at No. 4 on the Billboard 200 back in 2011. It rose to the third position the following week. If the new album sells more than 78,000 copies in its first week, Gomez could have her her largest sales week ever.
Her debut album "Kiss and Tell" was released in 2009, selling a slightly less than 66,000 copies in its first week.
The "Stars Dance" single "Come & Get It" peaked at No. 6 on the Billboard Hot 100 chart.
The singer's "Stars Dance Tour" kicks off on Aug. 14, with stops at the Barclays Center in Brooklyn and the Staples Center in Los Angeles. The tour will run through Nov. 27.
