The stunning identical twins involved in an alleged stabbing row over a man were known as the 'Croatian Kardashians' and were jealous of one another's looks, friends have revealed. Sara Grkovic, 22, has been arrested and faces an attempted murder charge after she allegedly stabbed sister Dajana because she was believed to be envious of her relationship with a man they both liked. Police were called to their home on Saturday night after a violent row which ended when Sara plunged a kitchen knife into her twin sister leaving her critically injured and fighting for life. The pair would compete with one another to post the most attractive pictures to Facebook, and would even jealously compare their looks with the other, according to friends.
