Scott Disick and Kimberly Stewart’s romance is affecting her relationship with brother Sean

Scott Disick and Kimberly Stewart’s romance is reportedly affecting her relationship with her younger brother Sean, who is ‘very protective’ of his longtime pal.

While the reality star, 39, has dated a slew of high-profile woman, including Kourtney Kardashian and Sofia Richie, a source told Page Six that the son of music legend Rod Stewart, 42, is ‘scared that Kimberly will break [Disick’s] heart.’ 

‘Sean is very protective of Scott,’ the insider revealed to the outlet, before claiming the siblings ‘do not get along at all.’ 

Apparently the source alleges that Kimberly ‘doesn’t think’ her brother is ‘smart’ and lacks ‘any ambition.’ 

‘He was constantly complaining about her. She bosses him around, yells at him and basically tries to tell him how to run his life,’ the insider revealed. 

Additionally, the informant stated that Kimberly seemed to be ‘jealous’ of the attention Sean received about his clothing line. 

‘Her relationship with Scott can’t make things any easier between the two siblings either,’ the insider explained.

The source noted that the trio are all ‘super dysfunctional’ and the siblings relationship is constantly ‘up and down.’ 

‘Now that Scott is back [in Sean’s life], Sean is being overly greedy about the time he’s spending with him,’ the source explains. 

Disick and Kimberly first sparked dating rumors back in 2015 after his split with Kardashian, but the model’s mom shut down speculation by telling the world they’re just old ‘friends’ and there was ‘absolutely no truth to’ the rumors.

‘They [the Stewarts] introduced Scott to Kourtney,’ Alana Stewart told People at the time. ‘I was there when it happened, so I can tell you they’re all great pals.’

Scott was then spotted hanging out with Kimberly, Rod, and her brother Sean in May as Kourtney prepared to tie the knot with Travis Barker in Italy and on a series of dinner dates over the past few weeks.
