Selena Gomez left Justin Bieber's new Hollywood Hills mansion on Friday morning after yet ANOTHER sleepover (the two spent the night last Saturday and on Wednesday night), and after that she went to lunch with some gal pals in Los Angeles.

We're thinking she showered and had a change of clothes at Biebs' house this morning -- if not, she's one dirty girl! But it definitely looks like that perfectly flat-ironed hair is from the night before ... gotta look good for the Biebs!

After lunch, Selena posted the video below and wrote, "Oceans -Hillsong church "spirit lead me where my trust is without boarders" so beautifully written. Have a great morning everyone!" Wonder if she sings these sweet songs to her man?

Despite the fact that JB has seemingly relished in the opportunity to rub his flings in Selena's face over the last few months, these two always end up back together. But how long will Jelena last this time around?! Be sure to cast your vote in our poll below!
