AceShowbiz - Irina Shayk celebrated her 38th birthday by going daring. The supermodel treated her Instagram followers to a slew of pictures of her rocking racy looks while partying with friends, including Emily Ratajkowski and Stella Maxwell.

In one of the images, Irina could be seen donning a high-necked, long-sleeved maxi dress with sheer fabric. The Russian model paired the dress, which perfectly hugged her figure, with minimal makeup as she styled her hair in mermaid-like waves.

She was seen posing with Emily, who went braless in an equally see-through lace top. As for Stella, the blonde beauty opted for a black velvet jacket for the bash.

In another picture, Irina enjoyed a snowy skate as she covered herself with a green bomber jacket. The mom of one could also be seen sharing a snap of herself posing with an elaborate display of white-and-green flowers.

The post also included a picture of her and her friends having a birthday dinner together. She also shared a photo of her birthday cake with the words "Happy birthday Irina" written on it. In the caption, she simply wrote, "Bday," alongside a red heart emoji.

Neither her ex Bradley Cooper, with whom she shares daughter Lea De Seine together, and former fling Tom Brady appeared to be present at the birthday bash.

Previous report claimed that despite their split, Irina and Tom still hung out several times. Of the catwalk beauty and the retired NFL star, a source said, "Tom and Irina have hung out a few times over the past several months. They never broke up because they were never an official item. So that's still where things stand between them."

The celebrity duo have been "hanging out here and there for a little while and enjoy the time they spend together." However, Tom, who has Benjamin, 14, and Vivian, 11, with his ex-wife Gisele Bundchen, as well as Jack, 16, with Bridget Moynahan, is currently focused on his children and he "isn't looking for a committed relationship at the moment."
