Pippa Middleton may purportedly be saying "I do" with city banker boyfriend Nico Jackson soon.

According to Celeb Dirty Laundry, Duchess Catherine's sister will be engaged to marry Jackson anytime now.

Kate is purportedly thrilled for Pippa Middleton and even allegedly helped Pippa's boyfriend pick out a ring for the proposal.

"Kate is so happy for Pippa and she loves Nico. They all get along so well!" a source reportedly told Life & Style. As for the engagement ring that Pippa's boyfriend bought, the source says, "It will definitely be a stunner!"

Aside from helping Pippa Middleton's boyfriend in choosing the engagement ring, the Duchess will also purportedly be well-involved in planning the wedding. After all, she of all people would know how to pull off a wedding of royal proportions after marrying Prince William in 2011.

It seems that the next weeks will be exciting for Pippa Middleton, as rumors surface that she is one of the godmothers chosen by Kate Middleton and Prince William for Princess Charlotte. Though the royal couple is yet to announce the godfathers and godmothers of England's newest princess, many are speculating that Kate's only sister will have a slot in the list after being passed over for Prince George.

"Top of the runners and riders this time is, of course, Kate's sister Pippa," Maxine Frith wrote in her article in London Evening Standard. "There was huge surprise when she wasn't among the seven people named as George's godparents but apparently Kate and William felt that she was already struggling to cope with the media spotlight focused on her since their wedding."

Many believe that Pippa fits the standards of being a role model for Princess Charlotte. The younger Middleton sister is working hard to make a name in the food writing industry, and her rumored upcoming engagement may seem to indicate her ability to balance career and personal life.
