Tiffany Trump spent some quality time with her nephew Theodore on Thursday.

The daugther of Donald Trump and his ex-wife Marla Maples shared an adorable snap of herself craddling her half-sister Ivanka's son.

"Missing this little [angel]" the 22-year-old recent college grad wrote alongside the photo.

Trump's newest grandchild, Theodore, will celebrate his 3-month birthday on Monday.

He is the third child of Ivanka Trump and husband Jared Kushner. They also have daughter Arabella Rose, 4, and son Joseph Frederick, 2.
