The brunette beauty, who is set to release her debut album, gave fans a glimpse into the photoshoot for her album cover.
In one snapshot, Lea is pictured looking gorgeous in a white cut out mini dress which shows off her toned midriff and long legs. The 27-year-old star strikes a pose and holds an intense gaze at the camera, as her make-up and styling team — who she has fondly called "Team LM" — proudly look on from behind her.

Lea couldn't resist sharing her excitement on set with her fans, as she took to Twitter to post more glamorous snapshots. The beautiful actress strikes another pose in a black and white shot, and shows off her incredible figure in a patterned long-sleeve crop top and high waisted hot pants.
"Thank you to the best team in the whole world today for an amazing shoot! @marktownsend1 @melaniemakeup @EsteeStanley @Ashlie_Johnson," wrote Lea at the end of the day.
"I'm so excited for u guys to hear my album. It's so special to me. I'm so grateful for u all. Thank u for giving me so much love & support," she added.
Lea has relied on her friends and family for their support, after the tragic death of her boyfriend and Glee co-star Cory Monteith, who passed away in July from a toxic combination of heroin and alcohol.
The young actress, who just last week paid tribute to Cory and his on-screen character Finn Hudson in a special Glee episode, has been gradually adjusting to her loss but is said to be missing Cory very much.
"Lea still misses him every day," an insider told People. "She talks about Cory all the time. She doesn't like to be alone. Her friends have really been helping her through it. It's getting a little easier."
Lea has previously spoken out about her late boyfriend, saying, "I really woke up every single day feeling like I was… in some sort of spell or something, that I was lucky enough to have him in my life.
"There was no greater man than Cory, so for the time we spent together, I consider myself very lucky."
