Eric and Lara Trump have welcomed their second child and President Donald Trump's  10th grandchild.

"@LaraLeaTrump and I are excited to welcome Carolina Dorothy Trump into the world. We love you already!," he tweeted just before midnight EDT.

On Tuesday morning, he tweeted a photo of the family and the newest addition.

Eric's older sister, Ivanka, sent the growing family her best wishes early Tuesday morning on Twitter: "We love you Lara, Eric, (big brother) Luke and sweet Carolina! ❤"

Eric later shared a photo of Carolina on Instagram:

Baby Carolina makes 10 grandchildren for President Trump, including her 1-year-old brother Luke. There's also Don Jr.'s five kids with ex-wife Vanessa: Kai, 12, Donald III, 10, Tristan, 7, Spencer, 6, and Chloe, 5. Ivanka has three children with husband Jared Kushner: Arabella, 8, Joseph, 5, and Theodore, 3.

Eric Trump, 35, is the third child and youngest son of the president and his first wife, Ivana. Eric Trump and older brother, Don Jr., run the president's company, The Trump Organization.

Lara Trump, 36, is an adviser to the president and host of his "Real News Update" who faced criticism earlier this year when she told 800,000 federal workers that the government shutdown may have inflicted a "little bit of pain," but was worth it.
