The 23-year-old model and Insurgent actress helped her little sis celebrate her 21st birthday that night, just one day after arriving back into town. She was spotted on Monday wearing her sweats while landing at Heathrow airport.
“Happy 21st little baboon!!!!” Suki captioned a photo she took of a Polaroid with Immy at the birthday dinner.
“Best bday celebrations! thank you @Blakeshotel @rayban @Kerznercalliva #Round
