The actress was spotted walking through a park in New York where she was filming for an upcoming episode of the award-winning musical-drama series.
She stood out from the NYC crowd in a bright magenta, double-breasted coat, which was cinched in at the waist with a belt pulled into a bow.
The 27-year-old (who plays the character of Rachel Berry in Glee) also wore a pair of black shoes with a chunky heel and tied her brown locks up into a smart ponytail.
Another behind the scenes shot shows Lea stood at a beautiful bridge while looking pensive.
It has been a tough summer for the Hollywood star, as her boyfriend and fellow Glee cast member Cory Monteith passed away following a drink and drugs overdose in July.
However, she has bravely returned to work and reprised the role of Rachel.
Glee producers are planning to air a special tribute episode for Cory next month, which will directly address the actor's battle with drug abuse.
The upcoming series will also see the addition of pop star Demi Lovato to the cast, who is set to become embroiled in a lesbian love affair with Naya Rivera's character, Santana Lopez.
