Ivanka Trump paid tribute to her sister by sharing a never-before-seen photo of the two during a cringe-worthy photoshoot that usually stays locked up in the family vault.
The eldest daughter of President Donald Trump posted the message Sunday morning as Tiffany Trump turned 26 years old.
"Happy, happy birthday Tiffany!You have grown into an amazing woman, despite my many babysitting fails!" Ivanka wrote.
The caption was alongside a photo of Tiffany as a toddler wearing nothing but a diaper and drinking a bottle while sitting on her older sister's lap.
Ivanka, however, is dressed in a luxurious all-black outfit of lace and frills, and striking a dramatic pose as Tiffany appears unamused.
Tiffany, who is Trump's only daughter with second wife Marla Maples, appreciated the message and responded, "Haha I love this and I love you so much!"
Fans of Ivanka also loved the photo, and one person let the First Daughter know, "This is beyond fabulous."
The sentiment was a bit warmer than her last Instagram post, which garnered lots of negative reaction as it came amid the tense situation in Turkey.
While sending out a similar, albeit less hilarious, birthday message to sister-in-law Lara Trump on Saturday, Ivanka was met with harsh criticism over her father's decision to pull US troops out of northern Syria.
Despite the negativity, Ivanka has remained focused on her own political work, especially in the field of child care.
Last week she met with officials in Kansas City, Missouri, and was photographed visiting classrooms.
"Kansas City certainly gave Sec. Azar, Sen. Blunt, Gov. Parson and me a warm welcome!" Ivanka later wrote.
She continued, "Hearing from parents, administrators (and kids!) alike about the challenges faced in the child care space was enlightening and this great feedback will inform our work back in DC."
