The players had to celebrate lifting the title - Liverpool's first in 30 years - alone in the stadium due to the COVID-19 pandemic.
But Lovren, who has since departed for Zenit St. Petersburg, couldn't help but immerse himself in the wild scenes.
"I did something that I don't know if anybody knows about. You are the first person that knows," Lovren told Sport 24.
"After the game, a lot of all the fans went to the stadium, it was a big party.
"They told us, 'Guys don't even go to the stadium because you will have problems, we can't keep you safe.'
"I said to myself, the party was almost over, 'I don't want to go to sleep, it's too early, at midnight' and I said to myself, 'I will take the car and go to Anfield, just to experience this.'
"I drove myself there, I have a video, I put the mask on and I went there. My god, tens of thousands of people celebrating and I just wanted to feel this emotion because we didn't have a good celebration in the stadium — it was empty.
"I needed to do it and I was really happy that I did it. It was a good experience."
