"The 18-year-old supermodel wore an itsy bitty, teeny weenie yellow snakeskin bikini while nonstop tongue-touching with her comedian boyfriend in Miami over the weekend. Gerber, the daughter of Cindy Crawford and Rande Gerber, was all smiles as she fixed her suit while playing at the beach with the heavily tattooed Davidson, 26. Davidson, who made headlines earlier this year for the large age-gap with former flame Kate Beckinsale, sipped happily on a Heineken while unashamedly flashing Polo Ralph Lauren boxers underneath his suit. Davidson and his new “princess” are vacationing in Miami to attend the wedding of one of his friends, according to E! News. The “Saturday Night Live” star recently took his new girl to an “SNL” afterparty. The couple was also recently seen showing massive PDA at a Charlotte Lawrence concert, and holding hands at an upstate grocery store. The lovebirds were first rumored to be dating in October, quickly after he broke up with actress Margaret Qualley.
