I wouldn't have thought you'll have many problems as actresses usually keep the branding they built up on their previous name. Plus she didn't use the name "Billy Evans" when she was with Chris.
All the best
Not true in relation to rights to a name - under UK law you would need to show either a registered mark or goodwill based on trade under the name.
There is guidance on the WIPO site on how things have been applied under the UDRP.
You may well be right about the second bit though.
