Rihanna flashed a massive diamond ring on her wedding finger yet again when she was spotted out Tuesday night in Santa Monica.

The 34-year-old is involved with A$AP Rocky and has reached the third trimester of her pregnancy with their first child.

When she emerged onto the sidewalk and was asked about the bauble, she laughed and teased: 'This old ring?'

What if...?: A previous sighting of the ring set off a storm of conjecture about the stage she has reached in her relationship with A$AP Rocky as they await the arrival of their child

For her latest night out on the town, Rihanna opted for a maternity mini-dress with a swirling chrome print that emphasized her blossoming baby bump.

Her restaurant of choice was Giorgio Baldi, a Santa Monica eatery that over the years has become a hot spot for celebrities.

Rihanna teamed her dress with a mosaic coat that featured fur lining and was done in a brown-yellow-orange-pink-crimson color stream.

Letting her luxurious dark hair tumble freely over her shoulders, the Barbadian bombshell accentuated her screen siren features with makeup.

She added an extra splash of glitz to the look with a dazzling necklace and balanced expertly on a pair of vertiginous ankle-strap stilettos.

Rihanna was previously spotted wearing a huge diamond ring on her left hand fourth finger while shopping for baby clothes this Monday.

The sighting set off a storm of conjecture about the stage she has reached in her relationship with A$AP Rocky as they await the arrival of their child.

In an interview that ran in Elle last week Rihanna spoke candidly about being pregnant, saying: 'There's also those days, girl. Especially in the third trimester where you wake up and you're like, oh, do I have to get dressed?'

During the run-up to giving birth Rihanna has received 'A lot of advice,' she revealed, elaborating: 'Probably the best advice is to sleep now because I won't get much later. I need to work on that before it's a thing of the past.'

Rihanna unveiled her pregnancy when she stepped out in New York in January with A$AP Rocky, her burgeoning baby bump in full view.

After the news broke an insider gushed to People that Rihanna 'couldn't be happier and is so excited to be a mom.'

Said the source: 'Having a baby is something she was never focused on, but being with Rocky opened her up to the idea.'

Being honest: In an interview that ran in Elle last week Rihanna spoke candidly about being pregnant, saying: 'There's also those days, girl' 

Rihanna and Rocky are 'just like any other pair of parents-to-be. Yes, they happen to be famous but they're just the cutest, giddiest young couple that's expecting kids.

To hear the insider tell it: 'A lot of guys have tried to sweep her off her feet, but Rocky actually managed to do it.'

Rocky is 'over-the-top romantic and sends her rooms full of flowers all the time. She's never felt this way before and this relationship has changed her.'

Giving the details: She disclosed that she was in her ' third trimester where you wake up and you're like, oh, do I have to get dressed?'

Pregnancy rumors went into overdrive in late November when Rihanna briefly placed her hands on her belly during a ceremony where she was named a 'national hero' by Barbados, which had just become a republic. 

During an interview with GQ last year Rocky called Rihanna 'The One' and spilled that: 'She amounts to probably, like, a million of the other ones.'

Rocky, whose own father was an immigrant to America from Barbados, called Rihanna 'The love of my life' in the interview.
