Paul Skenes appears to be on track to win the Cy Young AND Boyfriend of the Year honors this season ... as Livvy Dunne just revealed her MLB star BF showered her in gifts for her birthday.
The former LSU gymnast showed on her Instagram page on Wednesday that the Pittsburgh Pirates ace went all out for her 23rd ... throwing her a bash that featured balloons, cake and flowers.
There was also a sign on the wall that read "It's your birthday," and Livvy showed that some of the balloons even had real cotton candy buried inside of them.
