Battle of the Thick: BFFs Amber Rose and Blac Chyna exposed their assets as they party at Trinidad Carnival (WATCH VIDEO)

Amber Rose and Blac Chyna left nothing to the imagination on Monday as they partied the day and night away at Trinidad Carnival. The best friends both wore crop tops and impossibly tiny booty shorts, which left their famous derrieres firmly on display. See Photos and video after the cut.

Blac Chyna, 27, and Amber, 32, showed off their ample curves in the high-cut hotpants as they climbed onto the stage during the festival.

Amber's black short shorts were even more tiny than the grey ones that her best pal were wearing, and the pair also flashed their stomachs as they sported matching hooded crop tops.

The stars finished off their eye-popping looks with oversized sunglasses and red lipstick, and posted a series of selfies before heading to the carnival.

For one snapshot, Amber was seen wearing the red and black bikini that Blac sported just last week for a racy photo shoot.
