David Harbour's 'mistress' speaks out after Lily Allen exposes her in song

Lily Allen used her new album to lay out the heartbreak and betrayal she experienced in her and David Harbour’s broken marriage, and now the woman allegedly at the center of her marriage breakdown has spoken out.

In an interview with the Daily Mail published October 25, the woman accused of having an affair with Allen’s estranged husband has been identified as costume designer Natalie Tippett.

The 34-year-old met the Stranger Things actor, 50, in 2021 while working on the Netflix film We Have a Ghost in New Orleans.

“Of course I’ve heard the song,” Tippett told the outlet, allegedly rolling her eyes when asked about Allen’s new album West End Girl — specifically the songs Tennis and Madeline — which references the affair. “But I have a family and things to protect. I have a 2-and-a-half-year-old daughter, and I understand this is going on. It’s a little bit scary for me.”

Tippett reportedly began seeing Harbour, 50, during filming — with the actor allegedly flying her out to his home in Atlanta without Allen’s knowledge.

The singer later found incriminating texts on his phone, which inspired her scathing track Tennis: “So I read your text, and now I regret it… You won’t play with me and who’s Madeline?”

Allen, who married Harbour in 2020, filed for divorce last month following what she described as “emotional turmoil.” She later checked into a trauma treatment centre after learning her husband had allegedly maintained a three-year affair and even joined celebrity dating app Raya.
