Yes. It is highly unlikely, though. First of all, the woman would have to either ovulate twice in one month or have a single ovulation but have the egg split before conception (the first would result in fraternals twins, and the second in "half-identical" twins). Secondly, she would have to have sex with two different men within a very few days of one another (3-5). Third both fertillized eggs would have to implant, and both babies would have to survive the pregnancy; believe it or not, most twin conceptions result in only one baby.

YES! But fraternal twins ONLY,...obviously!
Not only is it possible for fraternal twins to have different fathers, it’s on the medical record books. This official medical term for this phenomenon is heteropaternal superfecundation.
The classic case was recorded in 1810 by John Archer, the first doctor to receive a medical degree in the U.S. According to Dr. Archer, a white woman who had sex with a black man and a white man within a short time of each other subsequently gave birth to twins—one white, one mulatto. Other cases have been reported since. And you thought this only happened with puppies?
Sperm cells can live inside a woman’s body for four to five days. Once ovulation occurs, the egg remains viable for another 12 to 48 hours before it begins to disintegrate; thus, the fertile period can span five to seven days.
Dr. Lawrence B. Werlin, founder and director of the Coastal Fertility Medical Center in Irvine, Calif., explains, “If the twins are fraternal, where two eggs (ova) are fertilized by two sperm and produce two genetically unique children, then one baby could be slightly older than the other. In addition, if a woman ovulates, releases two eggs and has intercourse with two different men, the eggs could be fertilized by both, resulting in fraternal twins with distinctive fathers.”
Historically, superfecundation has been difficult to prove, due to the crudeness of the blood-type testing methods. However, in 1978, Dr. Paul Terasaki of the UCLA School of Medicine reported in the New England Journal of Medicine that he and his colleagues had conclusively established a case of superfecundation using a sophisticated procedure called tissue HLA (or human leukocyte antigen) testing. Potential paternity-suit litigants, take note: This technique can also be applied to more conventional cases.

Absolutely. Fraternal twins come from two separate eggs. If a woman has sex with 2 different men when she ovulates, the babies could have different dads.

VERY X 1000 RARE! You have to have sex with TWO men in the same night or within a few days of each other while you are ovulating.
You would also have to be ovulating twice (two eggs) because they would have to be faternal twins.

technically yes. as long as you had sex with both men within a 24 hour or less period. and yes they have to be fraternal twins- as in dizygotic- as in the egg gets fertilized AFTER it splits into two. identical twins get their DNA (fertilized) and then split into two. so if the eggs split, and then get fertilized somehow by the sperm of different men, then you could have one of each.

It is theoretically possible for a woman to have two eggs during ovulation, and for one of them to be fertilized by one man and the other by a different man; but it must be extremely rare.

If they are fraternal they can have different dads. This is because two eggs are fertilized so it is possible that each eggs was fertilized by a different man's sperm.

Yes, if they're fraternal. It's called heteropaternal superfecundation. There was an article about that on MSN today.
