Gauff was relatively unknown outside of tennis circles heading into the pinnacle of the grass court calendar.
But "Coco" was the name on everyone's lips as the 15-year-old went to the hero Venus Williams in the first round.
The youthful exuberance and smiling nature endeared her to SW19 fans, from those in the show courts to those sitting at home.
The American proceeded to draw in the big crowds as she defeated Magdalena Rybarikova, double age, in the second round.
She encountered the first real phase of resistance when Polona Hercog took her on in the last 32, however.
Gauff lost the first set 6-3 but showed the metal as she won two tiebreaks to defeat the Slovenian across three thrilling stanzas.
There were fist-pumps aplenty from in the stands from the mother and father, and the majority of Court One was rooting for her on Monday against Halep.
It was not to be, though, as Gauff battled lost 6-3 6-3 – but how much money is she taking home?
How much did Coco Gauff earn from Wimbledon ladies ’singles?
For just showing up in the first round, Gauff banked a cool £ 45,000, eclipsing her usual pocket money.
Beating Williams bumped that up from £ 27,000 to £ 72,000, which then rose to £ 111,000 for making the third round.
With her thrilling win over Hercog, Gauff pocketed an overall £ 176,000.
Speaking ahead or the end-of-the-road match against Halep, Gauff said: “I've never hit with her or anything or practiced with her.
“I don't know how the ball would feel when I actually play.
“I think I'm just going to approach like every other match. I have been approaching.
"My routine has been working pretty well."
