Justin Bieber and Selena Gomez clearly can't say goodbye. A week after Bieber set people off again by posting a picture of the former (and now apparently, current again) couple snuggling with the message, "Our love is unconditional," the lovers were at it again on Monday night at Bootsy Bellows nightclub in Malibu.

In a brief video posted by singer and Bieber friend Khalil, the couple can be seen standing next to each other at a birthday party for longtime friend and videographer Alfredo Flores. Bieber, wearing a maroon shirt and his sunglasses at night stands next to Selena, dressed all in white, while a friend dances with a sparkler to 2 Chainz's "Birthday Song." While Bieber and Gomez are only briefly featured in the the clip, at the end you do see the pair leaning in and laughing together.

Flores posted a picture of the crew taking a ride on their three-wheeled motorcycles.

And later in the night a blurred picture of what appears to be Flores sitting next to Gomez in the club.

You may recall ... Bieber Instagrammed last week, "Our love is unconditional."

Sooo... definitely on again?
