Ali Lohan's new single "All The Way Around" has emerged as a hit on iTunes, maintaining a steady spot on the iTunes Top 100 since its debut July 14. Just as important to the 14-year-old is a vote of confidence from her singer sister Lindsay Lohan
, and her deejay gal pal Samantha Ronson.
"Lindsay loves it," Ali told PEOPLE in an exclusive interview. "It was nervewracking to hear from her because she's so hugely successful, so I was like 'No, don't listen to it!' I ran out of the room when she listened to it. She's really proud of me."
As for Ronson, "She likes it a lot," says Lohan, adding that "it would be really cool" for Ronson to play a remix version of the tune at one her deejaying gigs.
Lohan's next single will be called "Close That Door," which the singer-actress says "is about closing the door to the past, and all the negativity you went through in the past." Lohan, who's currently recording additional tracks for her upcoming album, also says she's "looking at back-up dancers" for an upcoming video and tour.
In fact, if her E! series Living Lohan,
also starring her manager-mom Dina, continues for a second season, it will likely focus on Lohan going on tour. "If anything, it'll be me on the tour bus. I’m not sure yet."
Also on the horizon: Lohan may head to China and Italy this fall to film the movie Troll
. " I got the role, but I'm still thinking about it," she said.
