Reese Witherspoon ... stunning in blue in Cannes.

Reese Witherspoon says she’s feeling great in her second trimester of pregnancy.

The 36-year-old actress is currently expecting a child with her husband Hollywood talent agent Jim Toth.

In recent weeks Witherspoon has been spotted playing tennis, going on hikes and attending several industry events.

Witherspoon was promoting her movie Mud at the 2012 Cannes Film Festival, where she spoke about how she is faring physically.

“The flight over was actually pretty good. I feel great," she told Us Weekly magazine. "I'm excited about showing the movie. The energy here is great!"

Witherspoon and her beau Toth attended The Paperboy after-party at Cannes on Thursday evening. Witnesses say Toth appeared to be especially supportive of his wife.

"She and Jim were talking closely. He was clearly protective of her whenever they were standing up or walking around, practically putting both arms around her," a source told the publication.

Witherspoon is already a mum to Ava, 12, and Deacon, eight. This is her first baby with Toth, whom she married in 2011.
