The actress, who was recently dumped by DJ Samantha Ronson following a
year-long romance, was seen flirting with the unnamed hunk at Planet
Hollywood Resort and Casino in Las Vegas - the venue for the after-party for
Mel B’s new burlesque show ‘Peepshow’.

A source said: “Lindsay had a brilliant time watching ‘Peepshow’ and was cheering and clapping throughout.

“At the after-party she focused her attentions on a good looking young guy
and the pair were quickly introduced. After swapping numbers they were
texting throughout – from opposite sides of the swimming pool.”

Lindsay and her new friend hit it off so well they left the event together
and reportedly ended up at the actress’ lavish hotel room.

The source added to Britain’s Daily Mirror newspaper: “They went on to a
comedy club before returning to Lindsay’s penthouse suite. It had a hot tub
and a marble cocktail bar – Lindsay was joking about making the most of all
the facilities.”

Earlier in the evening, the ‘Mean Girls’ star had a heart-to-heart
conversation with former Spice Girl Mel B and told the singer she was “back
on men”.

Last week, Lindsay was seen getting close to Leonardo DiCaprio at a
Hollywood party.

A source said: “As soon as Lindsay saw Leo she was like a bee to honey. When
she spotted him in a dark corner of the club she headed straight for him.
She quickly monopolized his conversation and made sure she had him all to
herself.”

However, Lindsay – who has sparked concern after partying hard following her
split from Samantha – was left disappointed when the actor shunned her
advances and left to spend time with girlfriend Bar Refaeli.

The source added: “They talked and Lindsay danced in front of him but
nothing happened. They went home separately.”
