Emma Watson's brother is to join the cast of 'Made In Chelsea'.

Alex Watson - who has appeared as an extra in the 'Harry Potter' movies on two occasions and has also modelled for Burberry - could be set to join the E4 reality show if it returns for a third series in 2012, as producers think he could make a great rival to Spencer Matthews as the show's alpha male.

Amber Atherton - who currently appears in 'Made In Chelsea' - told Closer magazine: "The producers think it would be amazing to get Alex on the show. He's good-looking so he'd make great competition for Spencer."

Emma has previously romanced current 'Made In Chelsea' star Francis Boulle, who then dumped her because she was too famous.

He recently said: "We had a bit of a thing a while back, but I have always been an ambitious person and I want to achieve my own notoriety for what I've done.

"That's why I chose not to pursue it any longer, because I didn't want to be the boyfriend of some child actress."

If Alex does join the cast of 'Made In Chelsea', he could be set to hang out in new Chelsea hotspot The Hollywood Arms, which re-launched last night (10.11.11). For more information see www.hollywoodarmschelsea.com
