With Kanye's wife Kim Kardashian West over in LA, it was left to the rapper to treat Kris to a night out after she flew into the UK on Monday (2 March).
Kanye's been in London since last week because of various work commitments including a performance at the BRIT Awards on Wednesday, 25 February.
He had been joined by Kim last week, but she flew back to LA on Friday to attend Ryan Seacrest's 40th birthday celebrations.
Yesterday, Kris arrived in London with Kim and Kanye's baby daughter North West, one. It's believed the family are stopping over in London before heading over to Paris Fashion Week.
There was no sign of North during Kanye and Kris' night out though perhaps that's unsurprising: she was probably exhausted after that long-haul flight from California!
Kanye is known to be very close to his mother-in-law, even referring to her as 'mum' in a recent interview.
His mother Donda passed away in 2007.
As well as taking Kris to dinner yesterday, the rapper travelled up to Oxford to deliver a speech at the Oxford Guild, where he reportedly told the students if he'd become an artist he would have wanted to be Picasso or greater.
