NEW YORK (AP) — Pop stars are lining up to make their debut in Facebook games from online game maker Zynga.

First came Dr. Dre and Lady Gaga. Next week, an avatar of singer Enrique Iglesias will join “CityVille,” Zynga’s most popular title.

Starting Tuesday, “CityVille” players on Facebook will be able to interact with Iglesias’s character when he visits their cities. Starting Tuesday, they’ll get to collect items the singer is known for and watch previews of his newest music video.

Zynga declined to give financial terms of the deal or say whether it plans more celebrity integrations, citing the fact that it is in a typical “quiet period” before its planned initial public offering. The San Francisco-based company filed registration papers in July for an IPO, and it’s expected to make its public debut this fall.

Iglesias said his team approached Zynga with the idea for a game integration and was involved from the beginning on the design and deciding what characters could do. They can collect virtual hats, boots, bling and a speedboat — representing the time Iglesias lived in Miami and owned one.
