Katy Perry and Ryan Phillippe deny dating rumours on Twitter

Singer Katy Perry and actor Ryan Phillippe have used their Twitter accounts to laugh off dating rumours.

The gossip began after the couple were reportedly seen together at Elton John's birthday party last month.

Phillippe, 42, used his Twitter account to try to put a lid on the chatter.

"I am not dating Katy Perry," Phillippe wrote on Sunday.

"Barely know her. Please stop flying helicopters over my house," he added. "She is not here."

"That's what someone who has Katy Perry in his basement would say," one user replied to Phillippe's tweet.

Perry, who ended her relationship with Orlando Bloom last month, used Phillippe's Twitter handle to issue a response of her own.

"Can you let me out of this basement please," she wrote on Monday.

To which the actor simply responded: "No".

Ending the exchange, Perry sent Phillippe one last message apologising for the rumours.

"Hi, nice to meet you, sorry about that Ryan Phillippe. Carry on."

Phillippe and his ex-fiancee, Paulina Slagter, split in November after five years together.
