Rihanna is definitely known for her partying ways and the singer has now reportedly angered fellow guests at London's fancy 45 Park Lane hotel with her "late night partying", with guests even allegedly leaving because of the star's ways.

RiRi angered guests recently after appearing on stage in Manchester an hour late, before she was then "pelted with chips" when she finally did arrive.

And it seems like the babe's behaviour just contines to get her in trouble, with sources now saying that she's been annoying her fellow hotel guests in London.

A source tells the Daily Star: "Rihanna or someone in her team set the smoke alarm off three times in her room so far."

"Other guests have complained about her playing loud music and partying."

Meanwhile, the Bajan star was also snapped engaging in some rather odd hotel behaviour earlier in the week, when she was caught sleeping in her tour bus despite for several hours, despite having a plush suite in the London hotspot.

The 25-year-old singer made a pit stop in Birmingham on Thursday night on her 'Diamonds' world tour before heading back to London soon after the show, arriving back at her Park Lane hotel at around 2am.

However, RiRi remained on the bus where she either slept or carried on the party for approximately three hours before finally emerging from the vehicle, huddled in a grey hoodie and a thick blanket, and making her way inside the hotel where she has stayed for most of this week.

Wonder if her tour bus sleepovers have anything to do with the "angry" hotel guests?
