It was sexy time in Paris for MELISSA GILBERT and her secret Ooh- la-la hunky new love!

Melissa Gilbert isn’t even divorced yet and she’s already found love again – with a handsome Frenchman she met during a solo trip to Paris over New Year’s.

Friends of the 47-year-old “Little House on the Prairie” star told The ENQUIRER she’s fallen head over heels for Thierry Gauchet, a 42-year-old vintage sports car salesman she met in the City of Light through a mutual friend.

Now the excited actress can hardly wait until Thierry – who runs the website www.luckyscars. net – visits her in Los Angeles for a romantic rendezvous. While he’s there, they’ll celebrate his April 30 birthday.

The twice-married star, now in the last stages of divorce from actor Bruce Boxleitner, is “crazy in love with Thierry,” revealed a close source.

“Ever since they fell for each other in Paris, they’ve been burning up the phone lines and carrying on the romance via the Internet.

“Thierry frequently phones her early in the morning for sexy wake-up calls.”

And while they’re apart, Melissa posts love notes for Thierry on her Twitter page.

On March 11, she left a simple, heartfelt missive in French, saying: “I love you always.”

She also purred that they could meet in their dreams and concluded with, “I’m yours, my man. Kisses…”

But all this romance isn’t sitting well with Boxleitner, her estranged husband of 16 years, who apparently still gets jealous.

“When Bruce saw sexy boudoir photos of Melissa and Thierry taken in France, he hit the roof,” said the source.

“But Melissa doesn’t care. She’s dreamily in love with Thierry, and they’re even talking about marriage.”
