The pair were seen enjoying their getaway for Memorial Day weekend in Cabo San Lucas.
On Sunday, paparazzi captured multiple photos of the rappers cuddling in the pool, per TMZ.
The "My Type" artist rocked long box braids and a hot pink metallic bikini; YG sported a black fitted as he affectionately wrapped his arms around Saweetie.
This is not the first time they've sparked romance rumors. In April, the two California natives allegedly snuggled up with one another at Coachella, following Saweetie's attendance at YG's birthday party the prior month. Also in April, the pair ate at Lala’s Waffles, Crepes & Shakes. The restaurant posted them in two separate Instagram Stories uploads, per HipHopDX. It praised Saweetie by writing, "We loved having such a humble sweet woman" and tagging her.
