The reality star and model, who turned 22 on Nov. 3, celebrated the occasion with the 28-year-old Los Angeles Clippers player Thursday at Petite Taqueria in Los Angeles, according to Entertainment Tonight.
People reported Jenner wore a crop top and jeans, but paired her casual outfit with $10,000 knee-high boots from Saint Laurent. Baldwin shared a photobooth snapshot with the "Keeping Up with the Kardashians" star on Instagram.
"Happy 22nd birthday angel face. I love youuuuuuu. To many more," the model, also 22, wrote.
Jenner and Griffin were first linked in September following the model's rumored fling with A$AP Rocky. Sources told People the pair are spending more time together and seeing where their relationship goes.
"They are seeing each other more, and Blake is doing everything in his power to make Kendall his girlfriend," an insider said.
"She's always working and traveling and knows a full-blown relationship isn't necessarily the best idea, but things are heating up," the source added.
