Rihanna showed off her burgeoning baby bump as she stepped out in Los Angeles for s spot of shopping on Monday.

The pregnant singer, who is expecting her first child with boyfriend A$AP Rocky, flashed a giant diamond ring on her wedding finger as she shopped for baby clothes at Kitson.

The Umbrella hitmaker, 34, donned a vintage Grave Digger T-shirt and a maroon and yellow baseball hat that read ‘Sex is Safer than Smoking’.

The nine-time Grammy Award winner bared a flash of her blossoming bump in the black graphic t-shirt that she paired with a pair of low-rise blue jeans.

The Barbados-born beauty wore her brunette locks down in natural waves and she toted a small gray Gucci handbag.

Rihanna sported brown fur stiletto sandals and accessorized her look with gold earrings, necklaces and bangle bracelets.

The We Found Love hitmaker was accompanied by a close family member on her outing.

The Fenty Beauty mogul was seen looking at baby clothes and toys while shopping at the upscale boutique.

At the end of her trip, an employee gave her bodyguard a number of shopping bags to put in the trunk of her car.

Last night, she dropped in on Instagram to share new video footage of her quickly growing bump.

The mother-to-be also showed off a new shade of lip gloss from her Fenty Beauty brand.

Rihanna donned a graphic t-shirt that was too small to contain her stomach as she wrote over the screen, ‘#preggoAF.’

She paired it with a pair of low-rise jeans as she started the video angled below her waist and showing a bit of her backside.

She gave her 124million followers a good look at her stomach and wrote in green typewriter font: ‘Takin “booty do” to new levels.’

After panning from her stomach to an upright position showing her full look, the pop star giggled to herself.

Rihanna wore her shoulder-length hair in natural-looking curls and arranged the front to fall over one side of her head.

She used a subtle filter over the snippet as she showed off the latest lip gloss from her cosmetics line.

Her lips were heavily coated with the bright pink shade and she puckered them while staring into the camera.

Riri said nothing but wrote over the clip, ‘I’m not gon’ lie we f****d this new lip gloss color UUUPPP!!! #BubbleBinge is easily my new obsession.’

With long, vibrant, almond-shaped red nails she held up a sample of the new lip gloss tube.

The billionaire recently opened up about her pregnancy and motherhood while launching her Fenty Beauty line at ULTA Beauty.

She told Elle she’s in the ‘where you wake up and you’re like, oh, do I have to get dressed?’ stage.

She explained, ‘Everything is a challenge, from getting dressed and how you’re going to do your makeup. But I like challenges.’

Rihanna, who is expecting her firstborn child with her boyfriend A$AP Rocky, dished: ‘There’s a pregnancy glow. There’s also those days, girl.’

The singer added, ‘Especially in the third trimester, makeup for sure helps you feel like a real person. I just focused a lot on moisturizing and on contouring.’

She reflected: ‘The face gets a little round and chubby. The nose starts to spread. Everything is a challenge, from getting dressed and how you’re going to do your makeup. But I like challenges.

‘I like things that force me to be creative and create in new ways. And with beauty, there’s so much that you can do.’
