Ryder 'thrilled for Portman pregnancy'

Winona Ryder has gushed that she is "thrilled" about Black Swan co-star Natalie Portman's impending motherhood.

Ryder - who became close with Portman while on the set of the ballet drama - told In Touch that she could not be more excited for her fellow actress.

"I’m so thrilled for her! Natalie’s just a precious gem to me," she said.

Portman announced late last month that she is expecting her first child with fiancé Benjamin Millepied.
