Ryan Reynolds and his wife Blake Lively have been engaging in a playful online banter, this time centered around her new haircare line, Blake Brown.

The 36-year-old actress spent seven years secretly developing the line, which will hit Target stores and online this Sunday.

Reynolds gushed about his wife’s achievement on Instagram, saying, “I’m obscenely proud of this woman…And the result is exactly what you’d expect of a hyper-obsessive, detail-addicted, uncompromising quality control genius. Also, I just found out her last name is Brown.”

Lively responded with a witty remark, saying, “Brown is my dad’s last name. He took Lively from my mom and older siblings. Now that I think about it, Ryan Lively has a nice ring to it. Your move, Reynolds.”

Lively’s beauty brand includes eight products costing under $25, including two kinds of shampoo, two nourishing masks, leave-in potion, mousse, but absolutely no conditioner.

In an interview with Vogue, Lively explained that she doesn’t know anyone in the entertainment industry who uses conditioner, adding that they use a different hair system than the one promoted to the mass market.

The married couple of 11 years are proud parents of three daughters – James, 9; Inez, 7; and Betty, 4 – as well as 16-month-old son Olin.

In a recent podcast interview, Reynolds shared that their kids can’t even fall asleep unless they’re in their bed, adding that it’s a fleeting thing.

Lively also recently shot a secret cameo as Lady Deadpool/Wanda Wilson in Shawn Levy’s MCU three-quel Deadpool & Wolverine, which has become the No. 1 movie in the world after amassing an eye-popping $545.9M at the global box office in its first week.

The R-rated three-quel starring Reynolds and Jackman currently has a ‘certified fresh’ 79% critic approval rating and an even better 96% audience score on Rotten Tomatoes.

Lively will also star in Sony Pictures’ romantic drama It Ends with Us, hitting US/UK theaters August 9, and has wrapped filming for the highly-anticipated sequel A Simple Favor 2.
