Its amazing how many people don't have a clue. This is entirely possible, though it does speak volumes as to the mothers active lifestyle. It is possible for two sperm to fertilize one OR to eggs, and there is no reason to believe that they HAVE to be from the same daddy. This is entirely possible, and has happened before. There have been cases where one twin is white and the other is black, or any other race for that matter.
I just learned on the National Geographic Channel that identical twins can be boy and girl, but it is rare. I didn't think this was possible, but it is. This is a facinating subject,

The term that I've heard is "dizygotic". (See link below for a little more information).
It's hard to believe that in this day and age people are so closed minded. It bothers me to know that for some, what they don't understand or don't know about is automatically something out of the "Twilight Zone" or something. No one knows everything. Maybe once some of the responders here realize that, they won't get so darned many thumbs down!

heteropaternal superfecundation, according to this website: http://www.dnacenter.com/media/twins-different-fathers.html
I didn't think there was an actual name, besides fraternal twins, but there ya go! I saw a case of that on the news, and another on a talk show a while back before that.
*EDIT* Wow! I just went back and read all the other answers, and everyone is so negative and disbelieving. Apparently, no one else watches the news.

This is highly unlikely unless the pregnancy occurred at a group orgy. Then you might get two separate eggs fertilized by sperm from two different males.
You are probably thinking of fraternal twins where there are two separate eggs and two separate sperm. These would have the same father and mother and be as related as other siblings. The alternative is identical twins where two embryos develop from the same fertilized egg.
But trust the Queen

They would be both fraternal twins and half-siblings.
Fraternal twins because they each originated from their own egg/sperm combinations (unlike identical twins which are the same egg and sperm which split).
And half-siblings because they have one parent in common.

I believe it's some type of parternal twins(different than Fraternal)

They would be fraternal twins (people not ALL twins come from the same egg!!!!!! DUH that's how there can be a boy and girl twin!!!!) They would also be half siblings.

Is that possible? Only one sperm cell fertilizes the egg. If more than one sperm cell reaches the egg, there will be a genetic defect. If this was possible the men would have to have had sex with the woman in hours.

It IS a reality and it is called heteropaternal superfecundation. I guess you'd call the twins heteropaternal twins...and you'd call their mom a skank!
