The 'Keeping Up With the Kardashians' star, 59, took to her Instagram account yesterday (28.03.15) to praise the 'Baby' hitmaker, 21, on the way he cared for her five-year-old grandson Mason - whose parents are Kourtney Kardashian and Scott Disick - while they were splashing about in the pool.
Alongside a photograph of Mason jumping on Justin's shoulders while playing in the water, she wrote: ''#Mason & @JustinBieber family pool day!!!#bestbabysitterintheworld (sic).''
And Kris wasn't the only one who enjoyed watching her grandson hang out with the pop star as Justin also shared the picture online and referred to Mason as a ''cool fan.''
Meanwhile, it's been a difficult few weeks for the 'Boyfriend' singer as he's recently been slapped with a lawsuit filed by his ex-neighbour Jeff Schwartz, who has claimed he and his wife have been left with ''emotional distress'' following allegations Justin and his friends threw eggs at his house last year.
Justin pleaded no contest to vandalism and was given probation after the incident but Jeff has demanded more because he believes his payout of $80,000 for repairs was not enough.
Over the past two years Justin has hit the headlines for his shocking behaviour, which has resulted in him being arrested a number of times, but it seems the hunk is trying to turn over a new leaf after he apologised to his fans during his roasting on Comedy Central earlier this month.
He said: ''I lost some of my best qualities. I'm looking forward to being someone to be proud of. Someone close to me once said how you rise from a fall is how you are truly defined as a man.''
The Irish folk brothers have plenty of stories to tell.
In terms of approach, 'Chain Tripping' takes some beating. To call Yacht's latest release conceptual would be underplaying its inspiration wildly.
On 'Tallulah', Grant Nicholas and Taka Hirose seem to have that burning connection again.
Burn My Eyes was released on this day (August 9th) in 1994.
With an eclectic mix of established acts, up and coming talent and resurgent household names, Neverworld once again offered up some superb musical...
