After spending Monday, June 16, riding on Bieber's motorcycle and partying with the 20-year-old at L.A. hotspot Bootsy Bellows, the "Birthday" singer took the party back to her house on June 17.
According to TMZ, the party got so out of hand that the cops were called.
A spokesperson for the Lost Hills Police Department tells Us Weekly: "We responded to a call at Selena Gomez's residence around 10:30 p.m. last night regarding one loud music complaint. The people contacted were cooperative and turned the music down."
According to TMZ, the party was so loud, that one neighbor claimed the "windows were rattling." However, a police source tells Us, "it was not a big party."
Gomez shared her own picture of the party the following day on her Instagram account, posting a black and white photo of friends around a white piano.
Gomez captioned the pic: "Tacos, live music and candles. such a beautiful night with beautiful people."
