Following an overseas trip which culminated with a stop at the brand new Atlantis hotel in Dubai, Lindsay Lohan is finally back home from her trip to Europe.

The “Mean Girls” starlet was spotted out in Beverly Hills sans Samantha Ronson as she headed to an appointment with her psychiatrist before doing a little shopping at Balenciaga on Tuesday (November 25).

While her twin sister is busy partying it up overseas at the Atlantis hotel in Dubai, Ashley Olsen was spotted hitting up the New York City party circuit on Thursday night (November 20).

Wearing a black robe-like ensemble, the twin mogul helped MANGO celebrate the relaunch of their Soho flagship store alongside company President Isak Andic, as well as Penelope Cruz’s MANGO designer sister Monica Cruz.

Despite the tough economic times being experienced around the globe, South African Casino mogul Solomon Kerzner is sparing no expense for the grand opening of his $1.5 billion Atlantis hotel.  And there are plenty of Hollywood hotties flocking to the massive event taking place tonight in Dubai.

Always up for a high-profile party, Lindsay Lohan and Samantha Ronson showed up on the red carpet looking excited to be part of the festivities.  Ronson will also be deejaying at the afterparty later this evening.

With such international appeal, it’s no wonder Kylie Minogue is one of the featured performers at the grand opening of the new Atlantis hotel in Dubai.

The awesome Aussie songstress arrived this evening to a flurry of paparazzi, looking simply stunning in a black and pink floral print dress with matching black heels.
