Justin Long was forced to move out of the California home he shared with comedy actor Jonah Hill - after realising they were acting "like an old married couple".
Long, now 30, set up a bachelor pad with 25-year-old Hill while they pursued their dreams of making it big as movie stars.
But Long, who's rumoured to be back together with on-off girlfriend Drew Barrymore, flew the nest after a string of nagging fights with Hill over how to keep their house clean.
He says, "We're still great friends but it got to be like an old married couple. We fought over recycling. He would recycle everything. I would find banana peels and shards of glass in the recycling bin. We started getting in little fights like that, he left the bathroom door open, didn't clean up after himself. Little things like that. It was time for a separation."
