According to Hollyscoop.com, the star was acting like a real Mean Girl on Thursday night when police were called to New York’s Bowery Hotel following a heated bust-up with her on/off girlfriend Samantha Ronson.

Sources claim Lohan “threw a room service tray at what she thought was her girlfriend’s door” — only to realise her DJ lover was staying in a different room.

Her outburst reportedly prompted complaints from other guests and police had to be called to the hotel to escort Lohan from the premises.

Temper, temper!

It must be thirsty work dating Lindsay Lohan…

Sam Ronson met up with her newly-blonde girlfriend outside a 7-Eleven in West Hollywood on Thursday – where they hung around in the car park for a chat.

DJ Sam propped herself on an upturned crate and guzzled a supersize soft drink while Linds crouched down and tried to hide from our snapper behind a parked car.

The on/off couple appear to be back on track after a shaky few months.  But is that what passes for a romantic night out in your world, girls?

Seems like we’ve all got Lindsay Lohan wrong.

Our favourite trainwreck is actually a workaholic, who’s toiling away on movie sets when she’s not stumbling out of nightclubs and locking herself out of Samantha Ronson’s house.

Lohan insists, “I do like to go out but there aren’t many girls my age who live in L.A. who don’t. But what people don’t realise is that I work very hard during the day. I am a very hard worker, there isn’t much time during the day when I’m not thinking about work. I enjoy going out but I enjoy working more.”

OK. So she parties all night and works all day.

Sorry Lindsay, but it was an easy mistake to make. The rest of us have to sleep.

They’re meant to be a young couple enjoying a second chance at love — but you could cut the tension with a knife when we ran into Lindsay Lohan and Samantha Ronson in Hollywood yesterday.

Observe Lohan shooting daggers at her lady love, who seems more interested in her Blackberry than making sparkling lunchtime conversation.

Is yet another split imminent?

Her on-off romance with Samantha Ronson might be the real deal — but these before and after shots prove it’s bad for Lindsay Lohan’s looks.

We caught the actress sneaking into her girlfriend’s pad in the early hours of Thursday.

And our vigilant snappers were still there when she emerged hours later, looking a shadow of her former self.

Lindsay had managed a change of clothes, but she looked pale and puffy — like Michael Jackson’s ginger twin.
