Pippa Middleton is reportedly planning to stop Prince Harry from bringing his lover Meghan Markle to her wedding this May.
A source told the Mail on Sunday, that Kate Middleton's pretty sister is determined not to be upstaged on her big day with fiancé James Matthews.
Pippa noticed how Suits actress Markle grabbed the spotlight last week when she attended a wedding in Jamaica with Prince Harry, the source said.
As RadarOnline.com has reported, Harry and Markle got lots of attention for holding hands and looking affectionate at their first major public event together--the Jamaica destination nuptials of pals Tom 'Skippy' Inskip and Lara Hughes-Young.
And that didn't go unnoticed by Pippa, whose sister Kate is married to Prince William, said the source.
"She saw how all eyes were on Meghan rather than Lara," a friend told The Mail On Sunday. "The situation was also stressful for Harry. Pippa and her mother Carole wonder whether Meghan's presence could cause a great deal of unnecessary chaos."
Also, Pippa, whose nuptials are set for May, is rumored to have told friends she'll be enforcing a policy of only allowing guests a "plus one" if they are married or engaged to their partner.
The "no ring, no bring" rule would disqualify Markle and Harry, pointed out the publication's source.
But since Harry, 32, and Markle, 35, have looked increasingly serious as a couple, royal insiders were expecting Pippa to make an exception to the rule to allow the Prince to bring his lady.

The incredible reaction to Markle attending Inskip's wedding has now made that doubtful, though, the source said.
Reports say Pippa and Matthews' wedding will take place in a private church in Berkshire in England, followed by a reception at her folks' home nearby.
Meanwhile, Harry and Markle's romance continues to make headlines. Last month, it was reported he introduced the actress to brother Prince William and wife Kate, and she also met their two children, little George and Charlotte.
