Jennifer Love Hewitt is reportedly pregnant.

The 'I Know What You Did Last Summer' actress is said to be expecting her first baby with fiancé Ross McCall in June.

A source said: "Jennifer was shocked, but at the same time she was ecstatic with the news.

"It wasn't planned, but now that it's happened Jennifer and Ross are both very happy."

Jennifer, 28, allegedly discovered she was pregnant the week before Thanksgiving in November, around the same time 'Band of Brothers' actor Ross proposed.

The happy couple marked their double celebration by jetting off to Hawaii for a romantic break, where Jennifer was pictured in a bikini looking larger than usual.

Her curvy figure sparked cruel comments and also got tongues wagging regarding baby rumours.

Jennifer - who appeared much slimmer in a recent advertising campaign for US clothing chain Hanes - hit back at the jibes about her weight saying she was proud of her body.

The brunette beauty fumed: "Size two (UK size 6) is not fat! Nor will it ever be. And being a size zero doesn't make you beautiful.

"I know what I look like and so do my friends and family. And like all women out there should, I love my body."
