AceShowbiz - David Harbour has reportedly found a new love with 27-year-old aspiring model Ellie Fallon. The 49-year-old actor best known for his role in "Stranger Things" apparently moved on, merely months after his separation from Lily Allen, 39.

A source close to Allen disclosed, "Lily is aware of the romance and has been very upset."

The new romance has come under scrutiny as his estranged wife opened up about her struggle with depression and eating disorder. The drama intensified with allegations that the relationship might have begun prior to the couple's official split.

Eyebrows were raised when Fallon posted a picture of herself smoking Harbour's favorite cigar brand back in October, several weeks before the couple's separation became public.

This led Allen, 39, to suspect that there might have been more to Harbour's interactions with Fallon than initially met the eye. "Seeing the picture Ellie posted of herself smoking a cigar, taken weeks before Lily and David called it quits, has convinced her that Ellie and David had been seeing each other before they split," an insider told the Daily Mail.

Adding fuel to the fire, it was discovered that Harbour had a hidden celebrity dating profile on Raya, a revelation that reportedly devastated Allen. Harbour, who had been living in Atlanta while filming the final season of "Stranger Things," is believed to have met Fallon in the city.

The controversy did not stop there. The two were also captured spending New Year's Day together in India and reuniting in Georgia recently, further confirming speculations of a blossoming relationship. The actor was also seen without his wedding ring at the Critic's Choice Awards earlier this month.

As for Allen, she seems to be channeling her energy into her work and personal recovery, and has been open about her struggles with mental health on her podcast, "Miss Me?"

"I've been spiralling and spiralling," she revealed during an episode in January. "I can't concentrate on anything except the pain I'm going through. It's really hard."

Following the emotional turmoil of the split, she took a break from limelight and checked herself into a clinic in the States. "I did lots of group therapy and some individual therapy and I just, I needed some time and space away from everything," she said recently.

While assuring fans she's in a "stronger" place, the British singer noted she still had a long way to go, "It's a journey. It's a lifelong journey of healing. It's not a quick fix."

With both individuals on their separate paths, the public continues to watch and speculate about the future of Harbour's burgeoning relationship with Fallon and Allen's journey toward personal healing.
