Blake Lively channeled her inner Baywatch babe in a racy red swimsuit while posing by the pool for a sexy campaign for her sparkling mixer company Betty Buzz.

While promoting her line of cocktail mixers, the actress, 35, shared a stunning snap of herself smoldering at the camera as she removed her t-shirt and put her incredibly toned midriff on display, just six months after welcoming her fourth child.

In the image, the Los Angeles native’s wavy blonde tresses were styled in pigtails under a reflective visor.

Like her bikini, her nails were painted dark red, which was the same shade as her lipstick.

She paired the image on her Instagram Story to the 2003 track, Stacy’s Mom, by Fountains of Wayne.

Additionally, the A Simple Favor star posed for a snap as she sunbathed in her backyard and sipped a sparkling lemon lime soda.

‘This is not a capture of a wild mating ritual. (though it could be),’ she joked. ‘I legitimately chug Betty Buzz Meyer Lemon, all day. Every day.’

She continued: ‘I am out number one customer. I respect our customer’s privacy so I won’t reveal that @vancityreynolds [her husband Ryan Reynolds] is out number 2 customer.’

Lively launched her sparkling mixers Betty Buzz in 2021.

That year, she revealed that she doesn’t drink.

‘I know that’s odd coming from the wife of an infamous gin slinger,’ she told People  while nodding to her husband Ryan Reynolds’ company Aviation American Gin.

She went on to explain: ‘Over the past many years of mixing, but not drinking cocktails, it became clear mixers are the unsung heroes of the drink world and deserve just as much love as alcohol.

‘We’ve spent the last three years crafting Betty Buzz and are so excited for people to finally taste it,’ she concluded in her statement.

She dished that the name of the line is an homage to the Lively name.

‘My dad’s name was Ernest Brown Jr but he was known as Ernie Lively,’ she told the outlet. ‘He gave up his last name when he married my mom and any success here, or I, have experienced has been in a name that isn’t his.’

Lively continued: ‘So when I was working hard to build this company, I wanted any success to be in a name that was meaningful to him. Betty was his mom and his sister’s name.

‘Also, Ernie would not be the best name for a mixer.’

In June, the mother-of-four raised plenty of eyebrows after announcing that her brand would be releasing alcoholic drinks, despite her being a non-drinker.

The backlash occurred after she shared a promo shot of herself showing the new drink selection, with the caption: ‘Drinking isn’t my thing. But for f* sake, flavor is.’

Fans quickly took to the comments to call out the Gossip Girl star, with one asking: ‘if drinking isn’t your thing… how do you know of [sic] it tastes correct or good?’

Some expressed that they found Lively’s entrance into the liquor space ‘irritating’ and that her caption seemed as though it was ‘shaming’ drinkers.

Another teased: ‘I don’t drink but you should [HAND ON FACE EMOJI]’

Many hoped she was introducing ‘non-alcoholic cocktails,’ so it turned out to be a disappointment.

One fan accused it of being a ‘cash grab’ while others compared her to Jennifer Lopez, who caught similar flack for the launch of her alcohol brand Delola this year.

In April, the On The Floor singer claimed she doesn’t ‘drink or smoke or have caffeine.’

In 2018, Lively claimed to be ‘an amazing mixologist’ despite not drinking.

She also told People that she does not ‘like the effects of alcohol’ and that she feels better sober.

‘I found that sometimes not drinking, the thing that was interesting was that it was a little alienating, because you don’t feel—and maybe it’s just in your own head—but you just don’t really feel a part of it,’ she expressed.
