Some people are not happy that the Duchess of Cambridge's sister Pippa Middleton and former cricketer Alex Loudon are back together. Parents of the latter are not impressed with Pippa's "too much partying" in London.

Reports said that the two just got together after their highly publicized split November of last year. However, Alex Loudon's parents think that Pippa is not good enough for Alex.

"They don't think Pippa's right for him as she parties too much," a source told Now magazine.

In contrary, the Middletons are happy that the couple is back together as Pippa was spottedleaving his house in the early hours of the morning following a late night rendezvous with beau.

The two broke up last year because Alex could not handle Pippa sudden rise to fame and their famous "bum moment" at the royal wedding last summer. Alex is simply unhappy with his life on the spotlight.

Alex's family, who live at Olantigh Towers in Kent and have a distinguished lineage, were reported not considering Pippa as a "wife material" for their son

According to a source of The Daily Mail, "Alex's parents were welcoming but they were always somewhat lukewarm about the relationship. They didn't see Pippa as 'wife material'. James and his wife Jane both come from very good families," quoted in a published report during the split of the two.

"Pippa is very sweet but she is socially ambitious - all her friends are so "trophy posh" it's ridiculous. They didn't honestly see Alex and Pippa's relationship as a long-term thing. James and Jane are very old-fashioned and prefer to keep things low-key," the source quickly added.

Reports say that Pippa is set to release a party planning book later this year and embark on a promotional tour of the US would surely not be welcomed by her potential in-laws.

It seems that there will be a delay on the possibility that Pippa will be joining her sister in the "Married Club."
