The 20-year-old reality star covered the lower half of her face with a jacket, but a dark mark was visible under her eye. Her 25-year-old boyfriend Travis Scott was spotted following close behind.
A source told PEOPLE, 'They [Jenner and Scott] were loving and affectionate the whole time.'
'The mark is probably just from being tired,' the source adds.
The doting parents were in Miami for Scott's appearance at nightclub, Story, on Saturday night.
Jenner was back in LA by Monday, showing off her daughter's nursery on Snapchat.
