Harry Styles might be getting on his One Direction band mate's nerves, but he's certainly got a legitimate reason, as he continues to spend time with Taylor Swift, this time spending the night with her in her Hollywood hills mansion. 

Suffice to say, the age-old proverb, 'bros before hoes' doesn't enter into Harry's head when making his evening plans. Plus, Taylor Swift is no hoe. The rumours that Styles and Swift were an item started when they were simply seen together, but now that they've been seen separately, leaving one another's hotels, the rumours have fast approached the status of fact. After Harry, 18, spent the night with Taylor, 23, at her house in the Hollywood Hills, and Swift's mother even came to visit for a surprise breakfast. A source told The Mirror: "They are getting on extremely well. After Harry spent the night at Taylor's house in the Hills, her mum made a surprise visit and joined them for breakfast."

While Swift is certainly a beauty, and a talented one to boot, Styles would be wise to heed caution. The country-pop-phenomenon has gone through men, or in Harry's case, boys, like strings on a guitar, and if the cute-couple do end up parting ways, Swift can expect to see a platinum selling single within 6 months. Hang on, we're starting to see a pattern here...
