[Warning: Potentially Triggering Content] Lily Allen was really going through it following the betrayal by David Harbour. As we previously reported, the pair broke up at the end of last year after she discovered her estranged husband had cheated on her. The Smile singer confirmed his infidelity in the lyrics of her upcoming new album, which she wrote in 16 days (!!!) following the split in December 2024. And we knew she wasn't "in a good place" because of the betrayal. However, her post-split struggles were far worse than anyone realized.
