Have a question for Mario Lopez?

The Saved by the Bell alum and current Extra host -- along with his fiancee, Courtney Mazza -- will be taking over Us Weekly's Twitter page on Wednesday afternoon to answer reader questions about anything from their engagement to their little girl to their current and past Hollywood projects (Saved By the Bell queries, anyone?).

Lopez and Mazza -- this year's Nivea celebrity couple, following in the footsteps of Bill and Giuliana Rancic -- may also dish on their four-year relationship and daughter Gia, 2.

To participate, send in your question now via Twitter to @UsWeekly using the hashtag #CelebsLoveUs. Lopez (@MarioLopezExtra) and Mazza (@CLMazza) will pick their favorites to answer starting on Wednesday after 3 p.m. (EST).
