Taylor Swift, Jonas Brothers

This won't be awkward at all.

Former feuding exes Taylor Swift and Joe Jonas will reunite to ring in 2009 together on Dick Clark's New Year's Rockin' Eve.

Swift and the Jonas Brothers are the latest acts joining the annual celebration, ABC announced. Lionel Richie has also been added to the lineup, which includes Natasha Bedingfield, Fall Out Boy, Jesse McCartney, Ne-Yo, Pussycat Dolls, Solange and Robin Thicke, who will perform during the Hollywood Party segments hosted by Fergie.

American Idol alum Kellie Pickler and Ryan Seacrest will also be on hand for the festivities, which kick off Dec. 31 at 10 pm/ET.

Swift and Jonas split in October when he dumped her over the phone during a 27-second call, she said on The Ellen DeGeneres Show. The country darling later added more fuel to the fire by saying Jonas cheated on her with actress Camilla Belle, a claim he denied on his MySpace.

Suffice it to say, they probably won't kiss at midnight.
