Part of dating a world-famous rock star is getting to go on tour. And Paris Hilton has (other than Prague) enjoyed herself while on tour with boyfriend Benji Madden.

Last Wednesday she was spotted leaving the Sanderson Hotel in Central London, sporting a Ferrari baseball cap and a Union Jack (UK flag) track jacket, paired with red track pants. Although it was a big shocking that she was sans her BM ring.

On Friday, the hotel heiress was out and about with Benji as they arrived in Gilgamesh restaurant in Camden for a late (11:30) dinner. From there, they hit up Crystal nightclub where they danced the night away, eventually leaving around 3:30am.

Earlier this week, Paris made some pretty unflattering comments about former BFF Kim Kardashian’s booty, comparing it to “cottage cheese inside a big trash bag,” during a radio interview.

But she’s since made amends. Hilton told press, “I was just joking around and I made a stupid joke. I felt really bad afterward, so I contacted Kim and apologized. It was a silly thing to say. Kim’s hot!”

And Kim seems to be over it. “Paris and I have been friends since we were kids, and I’m glad she made the effort to say she’s sorry.”

Paris Hilton hit the Royal’s favourite club, Mahiki, last night when in London with her boyfriend, Benji Madden.

Mahiki is the Mayfair haunt of the younger members of the Royal family. Prince Harry partied at the exclusive venue with Princess Beatrice, Princess Eugenie and Richard Branson’s daughter, Holly, earlier this month.

There was not a little dog or some “cute bows” in sight, as she had a much more “I’m with the band” look that she’s been rocking since she got with Benji, who is in England with his band Good Charlotte.

She had on a black pencil dress, silver jacket, silver shoes and a slash of red lipstick.

She did looked marginally happier than when she was snapped at the budget hotel in Liverpool, the Lord Nelson which costs £45 a night, last week.
