Jennifer Aniston's whirlwind romance with hunky actor Justin Theroux was barely out of the gate when she started flashing serious bling on her fingers. First there were his-and-hers "Jennifer" and "Justin" rings. And now a dazzling diamond on Jen's right hand is fanning rumors that the ex-Mrs. Brad Pitt has finally found "the one," version 2.0 - and that she and Justin might wed by summer's end.
They're kind of pre-engaged," a source close to Jen tells OK!. "We keep saying, 'What's with the rings? It's only been a few weeks!' But she says it feels right.' " Indeed, Jen seems radiantly happy. "She has a huge grin, 24/7," an insider says. "Her eyes have that extra sparkle."
And why is Jen so happy these days? "Her relationship with Justin is very physical," the insider tells OK!. "They're extremely touchy-feely, and apparently there are fireworks in the bedroom. It's been a long time coming for Jen- she's really missing the intimacy.
Meanwhile, friends say Justin is like a new man - inside and out. "He has always been somewhat cynical and pessimistic," the insider tells OK!. "But he has a happy, upbeat vibe now, like he's a better version of himself."
The couple finally went public with their romance on Wednesday night, walking hand-in-hand in London after a party celebrating the London premiere of her new film, Horrible Bosses.
