Call us crazy, but X17 is giving away two free Sidekick IIs!

To enter this contest, create your own captions for these celeb sidekicks – Ali/Lindsay Lohan & Blake Lively/Leonardo DiCaprio - as they chat on their cell phones.

Two contestants will win -- one winner per photo caption. They'll get T-Mobile’s endlessly entertaining smartphone in the mail for their efforts.

Be sure to include your REAL email address (which is viewable only by X17) when registering your comments so that we can contact you if you win. This contest is only open to legal residents of the United States (excluding Puerto Rico, the U.S. Virgin Islands, and other commonwealths, territories and possessions), 13 years or older.

We'll announce the two winners at noon PT this Wednesday so stay tuned!
