The former Celebrity Big Brother star uploaded a picture to Instagram on Thursday (1 May) showing herself beaming while taking a dip.
Really, could her bikini top get any smaller?!
Well, according to one Instagram follower it could, as they cheekily told her: "That bikini is too big. I think you can go a size smaller."
Regardless of what we think, however, from the smile on Courtney's face she's pretty pleased with her swimwear. She added the caption: "Pool fun. #happy #bikini #blonde."
Courtney found fame in the UK last year appearing in the series of Celebrity Big Brother that was eventually won by Charlotte Crosby.
After her CBB appearance 19-year-old Courtney split from actor husband Doug Hutchison, 53, who had supported her each week at the studio.
They have remained friends, however, and were snapped out shopping together in Los Angeles last month.
Courtney isn't home alone, though, as she's just adopted a gorgeous little Maltese puppy named Cupcake. "Loving my new little addition already!" she tweeted on 25 April. She's so precious ... & her name is Cupcake - she's just too sweet."
