Paula Abdul has split from her boyfriend.

The 'X Factor' judge and Jeff Bratton called time on their 18 month relationship in November and the record label owner has revealed it was due to work commitments.

He said: "Paula and I split in November. It was an amicable thing. But between the final months of 'X Factor' and my responsibilities with (my label) Cascine, there was little time for us."

The distance in their relationship is also said to have been a contributing factor, with Paula based in Los Angeles, while Jeff spends most of his time in New York.

The pair first met on a flight in 2010, but always made a joint effort to keep their romance out of the spotlight.

And Jeff is adamant he and Paula are still on good terms.

He explained: "We're still close. And I'll always be grateful for the time we shared as a couple."

Paula, 49, isn't the only judge on the new US version of 'The X Factor' to split from their boyfriend.

Nicole Scherzinger and her partner, Formula 1 driver Lewis Hamilton, ended their four year relationship in October due to work pressures.

However, the pair spent New Year's Eve (31.12.11) together at a ski resort in Vail, Colorado, and have both admitted since the break-up that they still have very strong feelings for one another.
