On a recent summer day in New York, newcomer Kat DeLuna would not let a little heat or humidity dampen her spirits. In fact, it appeared to only heighten her overall positivity. Of course, it doesn't hurt that DeLuna's debut single, "Whine Up" (featuring Elephant Man), is being championed across a handful of radio formats, including top 40, rhythmic, Latin rhythmic and rap. The techno-fueled track has even spawned the Whine Up dance, which DeLuna created while she was recording the song in the studio.

In this issue, "Whine Up" ascends The Billboard Hot 100 and Pop 100 to Nos. 35 and 23, respectively. "The single is going crazy," says DeLuna, a 19-year-old native New Yorker whose family roots can be traced to the Dominican Republic. "And I'm the very first Dominican crossover artist. I couldn't be more excited."

Epic has high hopes for DeLuna and her debut album, "9 Lives." Due this week, the Red One-produced collection finds DeLuna co-writing all but two songs. Taking cues from Sony BMG artists Shakira and Jennifer Lopez, the label is promoting and marketing DeLuna to English- and Spanish-speaking markets. And then there is the Whine Up dance, which has become a fan favorite on YouTube. For those in need of lessons, there is whineup.com.
