Alleged Affair Partner of Lily Allen’s Estranged Husband David Harbour Identified

Natalie Tippett has been identified as the woman allegedly involved with Lily Allen’s estranged husband, David Harbour.

In a conversation with the Daily Mail, Tippett, a costume designer who crossed paths with the “Stranger Things” star during a movie shoot in New Orleans in 2021, shared her thoughts on Allen’s new album, “West End Girl,” which addresses the affair.

In the track titled “Madeline,” Allen, 40, reflects on Harbour’s violation of boundaries in their “open” marriage arrangement.

“Yes, I’ve listened to the song,” Tippett told the publication, reportedly with an eye roll.

“However, my priority is my family and maintaining our privacy. I have a 2-and-a-half-year-old daughter and am aware of the situation,” the single mother stated.

“It’s a little bit scary for me.”

Tippett, 34, worked in the costume department while Harbour, 50, starred in the 2021 Netflix film “We Have A Ghost.”

Their alleged affair reportedly started shortly after filming began.

After filming concluded, the “Hellboy” actor allegedly flew Tippett out to his home in Atlanta — without Allen’s knowledge.

However, the “Smile” songstress found out about her husband allegedly cheating when she found texts on his phone.

When Tippett was asked by the Daily Mail if she knew her private texts with Harbour were being used in Allen’s songs, she replied, “Yeah. I just don’t feel comfortable talking about it at the moment.”

Page Six has reached out to both Tippett and Harbour for comment but did not immediately hear back.

In February, news broke that Allen, who married Harbour in 2020, and the actor were divorcing. The “Hard Out Here” singer then revealed that she had gone to a treatment center for “emotional turmoil.”

Allen filed for divorce last month.

Harbour has remained mum on the breakup and the infidelity rumors. In April, the “Black Widow” star awkwardly dodged questions about his estranged wife.
