How do I find the identity of a famous English actress I spoke to in London yest

Question:

How do I find the identity of a famous English actress I spoke to in London yesterday on the Embankment?

She was very short 5' 2" ish and petite build. Over 45 I would say. Can't think of anything else that is easily distinguishable about her.

I didn't speak to her first-the man she was with was asking us questions as we were supporting a canadian canoe in the Devizes to Westminster international canoe race and our crew were paddling the last stretch along the embankment after having paddled non-stop for over 24hours and the two of them were extremely interested in the race. It was as she spoke directly to me as she was leaving to cross the road that I recognised her as an actress. She is very quietly spoken with no regional accent. It is of interest to me who she is as we live out in the country and haven't visited London in over 30 years.
