Ex-Hollyoaks star sees Legally Blonde
The former Hollyoaks actress stepped out with boyfriend Matt Mills to see the production at the Savoy Theatre in London.
Pictures of the couple arriving at the venue appeared in the Sun, which swiftly commented on the outfit Rigby was sporting.
She turned up in a tiny black number which allowed her to flaunt her legs, although she complemented this with a large white blazer.
Rigby made her name playing Hannah Ashworth in Hollyoaks, but she left the Chester-based soap earlier this year.
One of the stars of Legally Blonde - Richard Fleeshman - also has extensive soap experience, as he used to play Craig Harris in Coronation Street.
He has also recorded an album and toured with the likes of rock legend Sir Elton John.
