Oscar-winner Hilary Swank has slammed reports that her marriage to actor Chad Lowe is in trouble because he's struggling to cope with her phenomenal success.

The "Million Dollar Baby" star was horrified by rumours that Lowe was seeing a Hollywood psychologist to help him come to terms with her glittering film career and save their 12-year relationship, the Internet Media Database reported.

She insisted that as a fellow-actor, he understood and supported her movie career.

She said: "Being married to an actor helps because he understands the ups and downs, and what they mean. It's not like Chad is going to get my roles. If you're not comfortable with someone's success, you shouldn't be with them."
