She really is in full bloom! Pregnant Tori Spelling enjoys some gardening with her brood

She's expecting her fourth child next month. 

And today Tori Spelling showed off her blossoming bump as she joined her children and husband, Dean McDermott, for a kids' event in Los Angeles.

The 39-year-old star hugged her growing stomach as she walked the red carpet in a flowing maxi dress, before joining little Stella and Liam for some family gardening during an appearance at the Boys and Girls Club of Burbank.

The actress worked on an arts and crafts project with her two eldest, Liam, five, and Stella, four, while Dean, 45, sat close by.

Tori looked radiant in a printed, spaghetti strap maxi dress that draped over her petite frame.

The mother-of-three swept her blonde bob to one side with a youthful braid, and with a lash of pink lipstick and eyeliner, was red carpet ready.

Tori isn’t one to shy away from showing off her frame.

The former Beverly Hills 90210 actress recently hit back at critics who claimed she should cover up her pregnancy curves.

Last week she took to her personal website to rant: 'A few months back, I caught a lot of flack on two separate occasions for baring my baby bump in a bikini and monokini while spending the day poolside with my family.

'I have to say, I'm super proud of my bump. Why should I be embarrassed and cover up something that's the greatest gift a woman can experience?

'A pregnant woman in any shape or size is beautiful!'

Tori and Dean, who married in 2006, share three children, with one on the way.

In addition to Stella and Liam, the pair are parents to 10-month-old daughter Hattie, and are expecting their newest addition some time in September.
