'Pregnant' Khloe Kardashian wows in summery off-the-shoulder blue mini dress as she attends Kim's lavish baby shower in LA (Details, pics)

She's reportedly pregnant with her first child with NBA basketball player boyfriend Tristan Thompson.

And Khloe Kardashian was positively beaming in a series of stunning photos taken at sister Kim's cherry blossom-themed baby shower in Los Angeles on Saturday. The 33-year-old fashion designer looked radiant as she laughed with friends at the star-studded affair.

The Keeping Up With The Kardashians starlet posed underneath blooming hot pink cherry blossoms which filled the entryway of Kim's Bel Air abode. Her endlessly long legs were on full display in a short periwinkle blue mini-dress which featured pockets along the sides.

The flowing straps of her see-through eyelet fabric dress slipped off her shoulders to reveal more of her tanned and toned arms.

Unique button detailing held the dress together near her neckline, with ruffled sleeves flowing down to her elbows. A matching baby blue belt wrapped around her waistline as she smiled for the gorgeous photo.

The Good American designer wore her long blonde hair in loose waves cascading down past her shoulder. She added a pair of towering stilettos to her already statuesque 5ft10in frame.

Khloe has made no mention of being pregnant and her mother Kris Jenner has only squirmed when asked if the star is with child.

Earlier in the day, Khloe took to social media after fans claimed the star's face looked a little different than usual.

Kylie Jenner is also reportedly pregnant with Travis Scott's baby, and Kim Kardashian has admitted her surrogate is due in February.

She captioned the sultry selfie, 'Haters will say it's photoshopped.'

This will be a third child for Kim and Kanye West as they already have North, aged four, and Saint, aged one.
