Jennifer Aniston and Justin Theroux are ''stronger than ever'' following their New Year break.

The engaged couple had been spending a lot of time apart toward the end of last year due to their respective filming commitments, but their trip to Cabo San Lucas, Mexico over the festive period gave them chance the get their romance back on track.

A source said: ''They're stronger than ever and the connection they had in Cabo is proof. The vacation was just what they needed, friends relaxation and lots of laughs. Jen and Justin make each other smile and everyone commented on how much they're back on form. They're in a really good place.''

While they have a wedding to plan - which is rumoured to be happening later this year - friends say Jennifer, 44, isn't planning to rush into having children.

The source added to America's OK! magazine: ''As she's said to friends on many occasions, when she found Justin, she wasn't looking for a baby daddy, she was looking for a life partner. That was her goal and if babies come around then fine. But right now its all about cementing their relationship.''
