You’d think that Beyoncé and Kim Kardashian would be great friends. After all, they have quite a lot in common. The pair are both married to famous rappers, are both mums to young children and are both used to the showbiz limelight. However, there have been rumblings for years that the two just don’t see eye to eye.

A recent report claims that their relationship has once again become strained – this time over their growing families. According to gossip website Radar Online, Queen Bey isn’t pleased that Kim’s been grabbing headlines with talk of expanding her own family with husband Kanye West. A source told the celebrity news outlet:

“Bey’s still irate that Kim hinted online she was trying for a baby the same day as she announced she was pregnant with her twins.”

The insider added:

“Kim wants twins via surrogacy so she can outdo Beyoncé.”

There’s also rumours that Kim is miffed that Beyoncé hasn’t arranged for their two young daughters to become friends. The source continued:

“The fact North hasn’t been invited to one play date with Blue Ivy also infuriates her.”

Kim’s people have been quick to dismiss the report, labelling it ‘absurd’ and ‘false’. However, Beyoncé’s reps have stayed noticeably hush on the matter. Of course, it’s likely that Queen Bey might just be too busy to reply to tabloid fodder right now. After all, the 35-year-old megastar will soon be bringing two little bundles of joy into the world when she gives birth later this year.

According to Mail Online, the pop princess has already started building a nursery for the babies at a cost of $500,000. It will, of course, include everything a child could ever want (and then some!) The bespoke nursery is said to include cribs, rockers, a state of the art sound system, a mini movie theatre and a custom fireplace.

So are Kim and Beyoncé friends or foes?

It’s rather telling that Beyoncé usually stays hush on such personal matters. In the meantime, it’s expected that she’ll devote the majority of her time to her little family, rather than an alleged feud with Kim.
