Ian Somerhalder and Nikki Reed are reportedly living under the same roof just three weeks after they started dating.

Somerhalder and Reed are said to have moved in together in Atlanta, Ga. where the 35-year-old actor is currently filming the sixth season of "The Vampire Diaries" with his co-star and ex-girlfriend Nina Dobrev, Us Weekly reported.  

"[Nikki] goes to set every day," a source told the celebrity and entertainment magazine, adding that the new couple also plans to share a place in L.A., too.

Earlier this month, Somerhalder also revealed that he and the 26-year-old "Twilight" alum have adopted a horse named Eagle.

"Proud new dad... What amazing creatures they are. Wow. His name is Eagle," wrote the "Lost" actor on Instagram on Aug. 5, along with a photo of him giving Eagle a hug. "Thank you @iamnikkireed for snapping this special moment, with our big baby boy."

Though they initially tried to keep much of their romance under the radar, the pair has gradually begun to display their affection to one another at recent events.

Just this Friday, Aug. 22, Somerhalder and Reed, in matching black outfits, both attended Heifer International's 3rd Annual "Beyond Hunger: A Place At The Table" Gala at Montage Beverly Hills in Beverly Hills, California, The Hollywood Life reported.

Though they arrived separately at the event, where Somerhalder was honored, the two sat at a table together for a cozy date night. And right before the hunky actor accepted his award, Reed, leaned in to whisper something into his ear and kissed him on the cheek, according to People.

The couple was first spotted in public together at a farmers' market in Studio City, California, July 20, where they enjoyed a cup of coffee and bought some goods.

"They were a bit affectionate and looked cute together," a source told People at the time. "Nikki looked giddy but also a bit shy about Ian's affection. You could tell that it's all very new and that they haven't dated for long."
