Beyoncé has officially launched her new activewear collection, adidas x IVY PARK, and it seems like she's turning Blue Ivy into a walking advertisement for it. Queen Bey and her 8-year-old modeled the clothing line while shopping in New York City during NY Fashion Week, and sent samples to her friend Kim Kardashian-West after Blue Ivy's adorable playdate with Kim's son Saint.

Blue Ivy Modeled Beyoncé's New Adidas Line

Beyoncé initially launched her Ivy Park activewear clothing line in 2016, but recently reintroduced the collection in conjunction with Adidas under the name "Adidas X Ivy Park." The line, which includes a variety of track suits, cycling shorts, sweatpants, T-shirts, and other attire, sold out minutes after its Jan. 18 release.

To further promote her Adidas collaboration, the award-winning singer and actress shopped around New York City on Thursday wearing Adidas X Ivy Park gear. She dressed her daughter Blue Ivy in a matching outfit, and the pair generated instant buzz as fashion experts were already in town for NY Fashion Week.

Blue Ivy's Adorable Playdate With Saint West

In addition to becoming a model for her mother's new clothing line at the age of 8, Blue Ivy is also getting an early start making some famous connections. A source told Us Magazine that she's becoming good friends with Kim Kardashian-West's son Saint, after the duo enjoyed a play-date together earlier this year.

Interscope Records co-founder and music executive Jimmy Iovine reportedly invited some close friends and their families over to his home, and Beyoncé's husband Jay-Z brought Blue Ivy, Rumi and Sir while Kim attended the gathering with three of her and Kanye West's children, Saint, Chicago and Psalm.

The source says that Blue Ivy spent her time playing with Saint, and noted that they have similar personalities, saying, "Blue is a tomboy and sporty, and Saint’s very active and has a ton of energy and a funny personality."

Kim And Beyoncé's Friendship Is Officially Back On

Jay-Z and Kanye West have been feuding since 2016, when West made complaints about Jay-Z skipping his wedding and not letting their children play together. Jay-Z followed up West's comments by saying that Kanye crossed a line and that he was unsure their relationship could ever be repaired. It seems that time is a healer, and their wives are back to being good friends.

Beyoncé sent Kim items from her adidas x IVY PARK collaboration, which Kim then modeled on Instagram while listening to the singer’s 2011 hit Run the World (Girls).

“There is literally the most amazing things in here," she remarked in another video, adding, “Thank you, Beyoncé, so much!”
