Jennifer Aniston is one very happy — and emotional — woman in love.
The actress was a guest on the first taping of her BFF Chelsea Handler's show Chelsea Lately in their new studio in Burbank, Calif. on Oct. 15. And when asked about fiancé Justin Theroux in her first interview since her engagement, Jen couldn't help but let her emotions get the best of her.
"Chelsea congratulated her on her engagement and Jennifer could not have looked happier," a guest at the E! taping tells Life & Style. "There was a second where she couldn't even speak, tears welled up in her eyes, and she had to pause to wipe one away."
The 43-year-old beauty, dressed in tight black pants over heels and a leather top that flared out over her waist, had no problem showing off her stunning engagement ring.
"You could see her gigantic ring across the room!" the guest tells Life & Style.
Not only has Justin won over Jen, but he’s also won over her friends.
"Chelsea said Justin is the absolute perfect guy for Jen," the guest shares. "Jen joked that Chelsea should follow her lead like she always does and 'do this too' [get engaged] while she placed her hand over her ring."
In August, Justin proposed to Jen, whom he's been dating since May 2011.
"I could not be any happier," Justin has said about his relationship with Jen, adding, "I always go to bed thinking I'm the luckiest guy in the world."
