The 'Same Old Love' hitmaker was noticeably absent from her close pal Taylor Swift's celebrations but managed to have a good time anyway as she held her own bash to mark the occasion.
Captioning a video of herself walking into the party, she simply wrote: "Hostess vibes. Happy 4th everyone! (sic)"
And the 23-year-old singer later appeared on Snapchat with her friends, singing along to Katy Perry's hit track 'Firework'.
Meanwhile, Selena previously revealed she is looking for a boyfriend she can have "fun" with.
When asked if boys were allowed to be a member of Taylor's infamous squad, she said: "I don't know. Find me a boyfriend and then we'll talk about it! I don't know. I like to have fun."
And Selena - who has been romantically linked to the likes of Orlando Bloom and Charlie Puth in the past - isn't keen on talking about her previous relationships, particularly her on/off romance with Justin Bieber.
She previously said: "At first I didn't care. To me it was: I'm 18, I have a boyfriend, we look cute together, we like that. Then I got my heart broken and I cared.
"Because people had no idea what was going on, but everywhere it was a million different things. I was kind of in a corner, banging my head against the wall. I didn't know where to go. I'm so exhausted. I honestly am so done. I care about his health and well-being. But I can't do it anymore."
