It looks as if Pippa Middleton's relationship with long-term boyfriend Alex Loudon could be off - again.
Kate's little sister, 28, is said to have broken-up with City broker Alex, 31, after a series of rows.
'She and Alex split briefly in the summer - but this time it's over,' claims a source.
'They are barely speaking.'
The pair have been together for a year and a half, but Alex is believed to have found it difficult to come to terms with Pippa's new sex symbol status after the Royal Wedding.
'Pippa tried to get over the split by spending last weekend with Wills and Kate at Balmoral,' the insider tells The Sun.
Pippa and Alex were last seen out together on 1 October at Boodles Boxing Ball in London.
