Fans were quick to send their love, with one writing: "It's insane how fast time flies by".
She also thanks fans for their support, saying "I love you thank you for the sweet love to baby True".
While appearing on UNINTERRUPTED's Road Trippin' podcast with Richard Jefferson and Allie Clifton posted on Tuesday, the 27-year-old National Basketball Association player broke his silence on the birth of his first daughter with Khloé Kardashian!
Most recently, the couple has made a decision to go public yet again.
Whilst Khloe, 33, has yet to share any photos of the little girl, her boyfriend has given an insight into what she looks like.
Thompson recently spoke about his daughter for the first time, while appearing on the Road Trippin' podcast on Tuesday. And baby True is eating, sleeping and sh*****g.
"She's 21 inches long", Tristan said about True.
"She's doing good", he said of his baby girl before shouting out his son from his previous relationship with Jordan Craig: "Let's not forget about Prince!".
This is the first child for the couple, who've been publicly linked since 2016.
A couple of days before True's birth, cheating allegations rocked Kardashian and Thompson's relationship.
A source told Us Weekly that Thompson "broke down crying in her hospital room after she had given birth", adding that he was "absolutely devastated that he had hurt and betrayed Khloé". Things seem to be going well for him post-cheating scandal. "They are anxious about Khloé - but she insists she's putting their baby first, and she wants to stay a family".
A day later, Kardashian cheered Thompson on at the Cavaliers playoff home game against the Toronto Raptors.
Meanwhile, his newest addition - who was born on April 12 - is keeping her activity to a minimum.
Tristan Thompson is opening up about being a father for the second time.
She has been cleared to work out by her doctors. Her family's issue with Tristan is that they think he won't change.
