Jennifer Aniston says she's "very happy" with boyfriend Justin Theroux.

The 'Horrible Bosses' actress - who started dating the handsome actor recently after first meeting him on the set of 'Wanderlust' last year - admits she's very content with life right now and knows how lucky she is to have met such a great guy.

When asked if she is happy on her personal life right now, Jennifer gave a small smile and said: "Yes, I'm very happy. I'm extremely lucky, and I'm extremely happy." 

The 42-year-old star - who has reportedly moved Justin in to her Los Angeles home - also revealed she is looking to buy a smaller home but hasn't found the ideal property yet.

Speaking on TV show 'Good Morning America', she said: "When I see it, I'll know what it is."

Friends have claimed Jennifer - who has had relationships with John Mayer and Vince Vaughn and was once married to Brad Pitt - is smitten with Justin and doesn't like to be away from him.

A source said: "Jen is totally into him. They have been hanging out for months.

"She wants to be with him all the time. She's diving in headfirst."
