The 20-year-old reality star and the 'Butterfly Effect' rapper - whose real name is Jacques Webster - welcomed their daughter Stormi Webster into the world just over two weeks ago, and the pair have now seemingly marked her birth with matching tattoos.
The dual inking reportedly took place when the pair went out on their first date night since becoming parents, and neither of them have yet told anyone what their new body art is of.
A source told The Sun newspaper: ''It was actually the first time they've been out on a date night since Kylie had Stormi. They went to a tattoo artist and got secret matching tattoo tributes to their daughter. They haven't told people what they got. Kylie organised it as a surprise and Travis loved it.''
The 'Keeping Up with the Kardashians' star and Travis, 25, already have matching butterfly tattoos, which they got last June.
Previously, a source claimed the loved-up couple have become even closer since welcoming Stormi into the world on February 1.
They said: ''Her relationship with Travis has made huge strides since having baby Stormi, and they are back in a good place.
''Travis has been staying overnight at Kylie's several times a week when he is not working or out of town and has also been giving Kylie her time to bond with the baby alone.''
And it was also previously reported that Travis - who recently pleaded guilty to disorderly conduct over an incident at a concert in Arkansas last May - has become a changed man since becoming a father.
A friend of the musician said that he is ''laughing a lot, and much calmer than usual''.
A source previously said: ''Kylie and Travis are a good team. Travis is able to do his own thing during the day as well, but he helps Kylie out at night. He has cut down on work and only has a few shows coming up.''
