After reconciling with their straying significant others in 2012, it looks like Robert Pattinson and Liberty Ross may have made New Year's resolutions to start over with someone new in 2013.

Pattinson has left Kristen Stewart, who cheated on him with her "Snow White and the Huntsman" director Rupert Sanders, a second time, according to The Sun.

The Twilight couple reunited in September after her admitted dalliance for the world premieres of the final installment of their film series, but sources told The Sun "his friends told him to focus on his career and said she was wrecking his chances.”

Meanwhile The Post reports that Sanders' wife, model Liberty Ross, has been spending quality time with music honcho Jimmy Iovine.

The two were spotted hanging out together at some Golden Globes parties, and a source told The Post "It’s early days, and there’s no indication anything has happened, but there is a lot of attraction between them.”

Ross was quoted in a recent video as saying: “We’re all on journeys, we’re all given lessons. Sometimes when things seem really bad, you have to be able to see the good and learn from it and move forward as graciously as possible. This year marked the end of some things and the beginning of something else. Beginnings and endings are always really exciting.”

Iovine split from his model wife Vicki Iovine in 2009.
