Bikini girl Katy Perry gets in deep with John Mayer as pair cosy up at Hollywood Hills pool party

It looks like things between Katy Perry and John Mayer are heating up.
The pair - who have been spotted stepping out together in recent weeks - are seen here putting on a tactile display at a friend's pool party in the Hollywood Hills.
Katy, 27, cavorted around in a sexy two-piece - while John Mayer, 34, shot her admiring glances, seen in one shot with a huge grin as he wraps an arm around her.

The couple are also seen together in the pool where, according to fellow guests, they put on a very flirty display.
Apparently John kept looking down Katy's bikini top as they shared a series of steamy, passionate kisses.
One guest told Star magazine: 'There was major chemistry between them... It was like they were on a honeymoon.'
The partygoer went on: 'John and Katy were all over each other.

'They were holding hands and kissing the entire time. Even in the pool, they stuck together non-stop.'
After spending a few hours at the pool party, John and Katy left together hand-in-hand, the source added.

Close friends of Firework singer Katy are said to be worried about her falling for the charms of badboy Mayer so shortly after her failed marriage to Russell Brand.
She apparently took a bit of persuading, but the ladies' man - who has dated the likes of Jessica Simpson and Jennifer Aniston in the past - eventually won her over.

Moving on: Katy and John spotted leaving a house party in Los Feliz last week and, right, Perry's ex-husband Russell Brand with new girlfriend Isabella Brewster

Perry and Mayer have been spotted enjoying each other’s company on several occasions in recent weeks; and earlier this month Katy was seen emerging from John’s car the day after a dinner date.
Katy's divorce from Russell Brand - who bears more than a passing resemblance to John Mayer - was made official last month, ending their 14-month marriage.
Since splitting from Russell in December 2011, the star has been linked to male model Baptiste Giabiconi and Florence And The Machine guitarist Rob Ackroyd, while the comedian has moved on with actress Isabella Brewster.
