Relationship Impossible! Lindsay Lohan, denies dating Tom Cruise, despite reports they had 'hooked up in London'

It certainly seemed to be unlikely romance.

Now, representatives for Lindsay Lohan tell MailOnline that there is absolutely 'no truth at all' to reports that emerged earlier this week that she is 'dating' Tom Cruise.

US publication OK! Magazine reported that the stars had been 'secretly seeing each other' after swapping numbers on October 7 at hotspot Chiltern Firehouse.

A source told OK!: 'Lindsay's always had a major crush on Tom and was dying to run into him, so the second she got her chance, she pounced.'

However, Lindsay's reps have now dismissed the claim. 

Tom - who is currently filming Mission: Impossible 5 in Monaco - and the 28-year-old star - who is living in London while she performs in play Speed The Plow - were said to be inseparable all night, according to the publication.  

Interestingly, Lindsay's name came up in claims made by Vanity Fair this year that Tom had auditioned a number of Hollywood starlets to be his wife before deciding on Katie Holmes (which was later denied). 

Lindsay denied she was involved in the story. At the time she tweeted: 'I just want everyone to know, that I have/had no part in the [Vanity Fair] story, nor has anyone in my life, personal and work related.' 

Meanwhile, Tom's ex Katie Holmes recently spoke out for the first time about her relationship with Tom following their split. 

Katie - who has 8-year-old Suri with ex-husband Tom Cruise - has revealed she doubts her parenting skills on occasions.

She told People magazine: 'You do the best you can. Some days you feel really good about yourself and some days you don't.'

Katie - who divorced from the Mission Impossible star in 2012 - believes support from other parents makes things a lot easier for her.

She explained: 'You really need to support each other, help people through whatever it is they're going through -- whether it's: 'My kid just threw a tantrum' or 'I was late for graduation' or whatever it is, you know!'

Meanwhile, the 35-year-old - who has help with Suri from a 'ready and willing' mother and nanny - has admitted she'd rather spend as much time as possible with her daughter.
