Eva Longoria Parker is sweet on chocolate and offering compassion to those in need.

The "Desperate Housewives" star spoke at a press conference today announcing a partnership between the Elton John AIDS Foundation and Godiva Chocolatier.

The actress helped introduce Godiva's Limited Edition True Love Heart Assortment and Valentine's Day Sweepstakes, which is projected to generate $200,000 for HIV prevention programs.

"I really love this new Limited Edition Valentine's Day box that honors Godiva's partnership with the Elton John AIDS Foundation," Longoria Parker said at the Los Angeles media event.

"It reminds us that love and compassion should always go hand-in-hand. I will definitely be gifting this to some of my loved ones this year and encouraging others to share a gift that gives back to those in need."

The boxes start at $25 and come with an access code, which you can enter for a chance to win.

So, what's the mouth-watering grand prize? The sweepstakes winner gets an all-expenses-paid trip to New York City in the fall, where he or she will receive red carpet treatment at EJAF's star-studded An Enduring Vision benefit.

Past attendees of the annual benefit have included everyone from Sharon Stone and Courtney Love to Daniel Craig and Bill Clinton.

At the event, the winner will present Sir Elton John himself with a $200,000 check on behalf of Godiva. The chocolate company will also make a $20,000 donation to a charity of the winner's choosing.

Candy with a cause. Sounds like a match made in heaven.

And here's another good cause we're happy to support.
