Earlier today (6 January), the Bajan superstar took part in the popular Instagram and Twitter trending topic '#ManCrushMonday' by posting a photo of Mychal on her Instagram page.
The sexy snap shows 23-year-old Mychal deep in concentration during a football game and kitted out in the colours of his team, the Philadelphia Eagles.
He's even working some black face paint under the eyes too. Very hot!
RiRi added the simple caption: "Is it Monday? Cuz chhh.... #MCM" to let all of her followers know why the handsome man had found his way onto her personal profile.
The 25-year-old songstress has been enjoying the single life since her second split from Chris Brown at the start of 2013.
As well as her '#ManCrushMonday' post, RiRi also uploaded a few selfies taken in New York over the weekend.
One of the pictures sees her sporting an eye-catching accessory on her tooth, although it is hard to work out whether the bling is gold, silver or in fact a tiny jewel.
Either way, this wouldn't be the first time that the pop star has been seen with a metal in her mouth.
Last summer, RiRi was snapped wearing a diamond grill on her lower teeth, which she teamed with plenty of matching jewellery.
