The High School Musical star also admitted that she was looking forward to keeping busy with work next year.
"We're good," Hudgens told People when asked about Efron.
The actress was celebrating her 22nd birthday in Las Vegas alongside High School Musical co-star Ashley Tisdale.
Hudgens and Efron were reported to have split up earlier this month after a four-year relationship.
"It's going to be a very, very busy year," Hudgens added, when asked what her plans were for 2011. "I have three movies coming out in the next year."
Hudgens stars in Beastly, alongside Alex Pettyfer, and Zack Snyder's Sucker Punch, both of which will be released in early 2011.
