The actor has reportedly signed up for exclusive dating app Raya, but has been using a fake name on his public profile, despite sharing his real picture.

A source tells the New York Post's Page Six the 31-year-old uses the alter ego to avoid attracting fame-seekers, but he quickly comes clean about his true identity when he connects with any promising matches.

"Kellan has been feverishly attacking the dating app scene," the insider says. "Even though he uses his own photo for his profile, he goes by the name 'Sebastian' before interacting with potential dates."

The movie star has yet to comment on the claims, but he has made it clear he wants to settle down sooner rather than later.

Last year (15), Kellan revealed he had set himself a five-year deadline to find the perfect partner and start his own family by 2020.

Speaking to In Touch magazine, he admitted he was actively "looking for that wifey" to spend the rest of his life with, adding, "I definitely want marriage and little Kellans running around!"

He went on to describe his ideal woman as someone who is "kind and genuine - and loves life and is willing to be adventurous", and warned a major turn-off is "someone who constantly checks her phone".

"It is important to be in the moment," he said.

Kellan previously dated 90210 actress AnnaLynne McCord and split from on/off girlfriend Sharni Vinson in the summer of 2013. He was most recently romantically linked to Playboy Playmate Brittny Ward.
