Demi Lovato is cooling her way to the top of the charts…

The 22-year-old part-Mexican American singer/actress’ latest single “Cool for the Summer” rises 3-1 in its second week on Billboard + Twitter Top Tracks chart (dated July 25). 

Lovato’s summer-themed single also rises in its second week on the Billboard Hot 100 chart, from No. 36 to No. 28.

“Cool for the Summer” ranks at No. 15 on the Digital Songs chart with 108,000 sold and No. 40 on the Radio Songs chart with 36 million in radio audience (up 29 percent).

The arrival of its lyric video on July 7 also prompts a 185 percent gain in streams to 2.4 million. Surely aiding streams: the clip’s high production value (at least for a lyric video) and pool-party eye candy.
