Camilla Parker-Bowles and Princess Eugenie are said to be seething with jealousy over Kate Middleton's popularity. The two British royals reportedly even insulted the Duchess, claiming she is only good at making babies.

Sources told gossip site Celebdirtylaundry that both Camilla and Eugenie clearly share the same dislike for Kate Middleton. The two have reportedly been very vocal with their insults towards the Duchess. Behind her back, sources claimed Kate Middleton was labeled as "commoner Kate" who is only good at "breeding and birthing more heirs to the throne."

Additionally, sources claimed the two royals also accused Kate of worming her way into the royal family because of her "excellent fame game" and not because she "earned it. For Camilla Parker-Bowles and Princess Eugenie, the Duchess of Cambridge will allegedly always be an outsider in their eyes.

Furthermore, Prince William's cousin and stepmother are said to be jealous over the attention that Kate Middleton is getting from the media. She has allegedly been stealing the limelight away from Camilla Parker-Bowles and Princess Eugenie ever since she married Prince William. Inquisitr adds the media coverage only increased with her first pregnancy and birth to Prince George. Now people are all over her following her confirmed second baby. In a sense, Kate Middleton has veered from a "commoner" to the Duchess of Cambridge and now she reportedly already holds a celebrity status.

Camilla's ill-feelings towards the Duchess are not surprising. According to Celebdirtylaundry, she has supposdly expressed her dislike for Kate Middleton before. However, it's said to be a surprise knowing other extended family members of Prince William also share the same sentiments towards the Duchess.

However, Camilla Parker-Bowles' supposed dislike for Kate Middleton could be mere speculation. Camilla and Kate have never personally expressed their displeasure for each other. Camilla has also not commented on any reports of her rumoured ill-feelings towards the Duchess.

Clarence House announced Kate Middleton's second pregnancy last Sept. 8 through Twitter.
