Then + Now: Nicholle Tom from ‘The Nanny’

Beautiful blonde teen actress Nicholle Tom played shy Maggie Sheffield on the hit '90s series 'The Nanny,' but what's she up to these days?

Then: 

Nicholle Tom got her first big break on 'Beverly Hills, 90210' playing Sue Scanlon, Scott's sister. She went on to star in 'Beethoven' and 'Beethoven's 2nd' (those dog movies), and reprised her role from those films by lending her voice to the short-lived animated series.

But everyone probably knows her best from 'The Nanny,' the '90s sitcom starring Fran Drescher as a Jewish woman from Queens who becomes the nanny to the three children of a wealthy British composer. Tom played Maggie Sheffield, the eldest daughter -- she starts out shy and bookish, but thanks to a little help from her new nanny, really comes into her own.

Now:

'The Nanny' ended in 1999, but Tom's career didn't. She's starred in a handful of small movies, but she's been all over television -- she was the voice of Supergirl on the 'Justice League' animated series, and in recent years she's popped up on 'Burn Notice,' 'The Mentalist,' and 'Castle.'

Up next for Tom? A recurring role on the much buzzed-about new Showtime series 'Masters of Sex.'
