Rihanna has brought new meaning to the word lip service after lending her famous pout to the promotion of her latest Fenty Beauty gloss in a stunning campaign.

The 33-year-old chart topper posed for a series of sizzling images in which she can be seen modeling her new $22 Gloss Bomb Heat Universal Lip Luminizer + Plumper while posing in a plunging flame-orange shirt against a fiery backdrop.

Sharing the snaps on Instagram, Rihanna praised the cherry-red gloss’s pout-plumping abilities, promising her fans that it will leave them with ‘juicy, glossy, plumped-up lips’, while showcasing the formula on herself.

The pH๏τos sees Rihanna pouting up a storm while striking a variety of poses to ensure the camera caught her lips from every possible angle.

According to the Fenty Beauty website, the gloss contains an ‘innovative blend of ingredients’ – which it refers to as its ‘Plump Job Complex’ to naturally enhance the pout, including ginger root oil and capsicum fruit extract.

‘Give your lips an Instant Plump Job with Gloss Bomb Heat,’ the online description reads. ‘This shimmer-free lip luminizer and plumper hybrid delivers a hint of tint, and fuller-looking lips—thanks to an innovative Plump Job Complex.

‘Your lips are ready to come out and play. Picture the original Gloss Bomb you love, with no shimmer, a hint of tint, and a gently тιтillating and warming sensation that leaves your lips feeling smooth and looking fuller—that’s Gloss Bomb Heat.’

The singer paired the ‘H๏τ cherry’ gloss with a smoldering smoky eye – and picked the perfect fiery ensemble to complement the ‘H๏τ’ product, modeling an orange-red low-cut silk shirt and high-waisted leather pants from LaQuan Smith.

She added plenty of accessories to her look, which included large hoop earrings, a few statement rings, and a chunky necklace.

Rihanna also flashed several of her tattoos in the sH๏τs, including a henna-inspired art on her hand, the phrase ‘never a failure, always a lesson’ on her right shoulder, and the top of the Egyptian goddess Isis, which she has inked onto her ribcage.

The popstar’s tattoos have become the subject of much speculation this week after it was revealed that Rihanna has covered up a shark inking on her ankle, which she got to match her ex-boyfriend Drake.

Rihanna was first seen with a distinctive shark tattoo around September 2016, and just weeks later, her then-boyfriend Drake, 34, was spotted with a strikingly similar inking on his right arm.

However, there was no sign of the tattoo while she enjoyed a Sєxy date night out with new boyfriend A$AP Rocky in New York on Wednesday night.

The Barbadian popstar proudly strutted her stuff as she stepped out in the Big Apple, showing off new tattoo on her left ankle that appears to have been inked over the shark design.

Rihanna and Rocky looked every inch the blissful couple as they enjoyed their evening on the town, which came just weeks after the rapper referred to the singer as ‘the love of his life’.

The loved-up duo were pictured kissing and hugging while seated inside bar, looking as though they only had eyes for one another.

Beauty brand founder Rihanna put on an incredibly stylish display in a figure-hugging pink dress, which she paired with gold strappy heels, a vintage Fendi bag, and a fluffy pink hat.

Once inside their chosen date night venue, she layered her boyfriend’s leather jacket over the dress to stay warm.

The songstress certainly had plenty to celebrate – after her new Fenty Beauty gloss debuted to rave reviews from fans, who waxed lyrical about its plumping abilities.

‘I love this! I just picked it up today so I’ve only tried it once but it’s wonderful,’ one Sephora customer wrote.

‘The plumping starts pretty immediately but I find it to be fairly mild which I actually prefer to the plumbers that make your lips swell fifty times their normal size.

‘It feels and looks similar to when I eat something with H๏τ sauce on it, and adds a beautiful sort of stain to the mouth after you remove it.’

Another person said of the gloss: ‘Purchased this the day it came out and I love it! The amount of tint is just right and I definitely notice my lips look plumper.

‘My lips tingled for just a bit after application. The formula is not sticky but is very shiny. Overall very pleased! I am very fair skinned and I love the color on me.’
