The couple are now parents

Evan Rachel Wood and husband Jamie Bell are celebrating the healthy arrival of their first child.

The happy couple – who married in October 2012 – welcomed a son yesterday.

‘Its a boy!! Song of the day “beautiful boy” #johnlennon,’ Tweeted Evan, 25.

Evan and Jamie, 27, started dating in 2005 after starring together in the video for Green Day‘s Wake Me Up When September Ends.

They broke up a year later but got back together in 2011 when Evan ended her long-term romance with rocker Marilyn Manson.

Billy Elliot actor Jamie revealed on Twitter last night how proud he is of Evan for handling the delivery of their little one so well.

‘Wow! What a day. Evan you are my warrior! You never cease to amaze. Thank you for birthing our son so naturally & peacefully. You did it!’ Tweeted Jamie.

Evan replied: ‘And you are mine 🙂 thank you for being there and helping me through it. I love you both more than words can say. @1jamiebell.’
