Got plans on Wed., Oct. 26 at 7:54PM ET? Well, now you do and you're going to need an umbrella, especially if you are a Twihard. Bruno Mars will be premiering his video for 'It Will Rain,' which lives on the 'Breaking Dawn' soundtrack. The vid will debut on MTV, so be sure and park in front of the tube by 7:44, just to be on the safe side, since this is one premiere you don't want to miss.

If your dance card for the entire night is free, then you should plan to head over to after the premiere to enjoy Sway Calloway's exclusive chat with Mr. Mars himself. As if that weren't enough -- and this news should delight Bella and Edward Cullen fans -- 'Twilight' music supervisor Alexandra Patsavas will be on hand to discuss all the musical elements of the latest installment of the vampire franchise.

If you have burning questions for Mars, start submitting them today via or via Twitter at the #AskBruno hashtag.

The soundtrack for the film is due out Nov. 8 so this premiere should ramp up excitement for that date. Both of these elements should also stoke the fires of excitement for the film, which hits multiplexes on Nov. 18.

Live fast, Twihard!
