Rita Ora at Diane Warren’s Birthday Party in LA

The singer puts on a busty display and exposes her waistline in a plunging black cardigan at Diane Warren’s birthday party in Los Angeles.

Seaside was a collaboration between her and songwriting legend Diane Warren. As Rita Ora donned her glad rags for Diane’s birthday bash in LA, she exposed her cleavage and slim midriff.

Her plunging black cardigan showcased her ample assets as she headed up to Gracias Madre WeHo’s restaurant.

Wearing heeled sandals, Rita matched her raunchy top with black high-waisted slacks. In addition to the large pink plastic chain necklace, she wore matching earrings and a black purse to carry her essentials.

As she framed her face with strands of curly hair, she threw her curly locks into a messy updo on top of her head.

Rita Ora donned a full face of glam makeup, including a winged eyeliner, sparkly gold under-eye makeup, and nude lipgloss. While attending her friend Vas Morgan’s birthday party, the star looked stunning alongside her close friend.
