Looks like Ian Somerhalder
has been bitten by love.
The Vampire Diaries
star is "very serious" about his new girlfriend, Twilight
actress Nikki Reed
, a source tells PEOPLE.
While, at first, they tried to keep much of their romance under the radar, they've slowly started to share some sweet moments at recent events and on social media.
On Friday, the pair attended Heifer International's Beyond Hunger Gala in Beverly Hills, where Somerhalder, 35, was honored. Though they arrived separately, the pair sat at a table together for a cozy date night. Then right before Somerhalder accepted his award, Reed, 26, leaned in to whisper something into his ear and planted a kiss on his cheek.
Earlier this month, Somerhalder posted a photo to Instagram
that revealed that the two have already started a family together
: They are the parents to a horse named Eagle.
"Proud new dad … What amazing creatures they are," he wrote. "Thank you @iamnikkireed for snapping this special moment, with our big baby boy."
The low-key couple were first spotted out together
at a farmers' market in Studio City, California, July 20, where they sipped on coffee and picked up 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."
Their budding relationship comes months after Reed announced her amicable divorce
from musician Paul McDonald in March after 2½ years of marriage. Somerhalder split from costar
and longtime girlfriend Nina Dobrev in 2013.
