Los Angeles, Dec 29 (IANS): Actress Jennifer Aniston has left for Mexico to welcome the New Year with her actor-fiance Justin Theroux.

The two were spotted leaving a private plane with their entourage in Cabo San Lucas Friday, after celebrating Christmas with Theroux's family in New York City, reports contactmusic.com.

A source said the couple had relationship counselling and were determined to make more time for each other in 2014.

"Jen and Justin love each other, they are fully committed. They had hoped to be married by now but work commitments this year meant their plans went astray. They have had some counselling. They both regret not spending more time together this year. They're determined next year will be different," the source said.

"Jen and Justin are looking at it like it's a party for their friends. They've downgraded the scale of their wedding. Justin is adamant it will happen in 2014 but that it will be more, 'spontaneous and organic' than they'd previously wanted," the source added.
