Evan Rachel Wood has given birth to a baby boy.

The 25-year-old actress and her actor husband Jamie Bell have confirmed the arrival of their ''beautiful boy'' but gave no other details.

Her representative said: ''Evan Rachel Wood and her husband Jamie Bell are parents to a beautiful boy. Parents and baby are all doing well.''

Evan rekindled her relationship with 'Billy Elliot' star Jamie, 27, in the summer of 2011, five years after they initially broke up.

The lovebirds - who got matching tattoos of their initials soon after they first met - wed in October 2012 and announced they were expecting their first child in January 2013.

Evan recently revealed that although she loved being pregnant, it wasn't always easy.

She explained: ''It's been a whirlwind roller coaster, it's been amazing. But it's not easy.

''I've been really tired and gone through different cravings but nothing really weird has happened. Pickled onions may be the weirdest thing I've craved. Oh man, I couldn't get enough pickled onions.

''I've been doing yoga and walking, you're supposed to walk five times a day.''
