Ben Stiller: Jen Aniston, Justin Theroux Are "Really Happy Together"
"They seem to be really happy together," Stiller, 45, told Us Weekly at the Tower Heist premiere in NYC Monday. "They're both great people. I love them both."
Though Theroux, 40, has been shacking up at Aniston's recently renovated NYC penthouse, their future together remains uncertain.
"I've been married once and I don't know if I'll get married again," the 42-year-old actress added. "I can tell you that as of this very moment, as of today, I have no plan to get married."
