Are Hollywood actors Hayden Christensen and Rachel Bilson back together? Hayden and Rachel are apparently dating again, after calling off their engagement three months ago.

People reports, quoting an unnamed friend of Rachel Bilson that the two are seen together just three months after they decided to break up due to the physical distance between them. Hayden Christensen is based in Canada, while Bilson lives in Los Angeles. The distance is what allegedly cause the break up back in August.

The two met while filming for the 2007 film Jumper and were engaged in December 2008.

Christensen was spotted leaving Bilson's California house which may have sparked the rumours that the two are again a couple. But there's nothing wrong if the couple are giving their relationship a second shot, because, as they say, love is sweeter the second time around.

However, both sides are yet to deny or confirm the rumours of renewed romance between them.

Meanwhile, Christensen will star as a bank robber yet again in Columbia Pictures' Takers.

In the film, Hayden plays AJ, a member of a group of young criminals who rob banks to sustain their lifestyle. The group is chased by a dedicated police as they stage bank robberies after another.
