Pippa Middleton is showing that she could be a good mother as she spoiled niece, Princess Charlotte, rotten. Is the 31-year-old dropping a hint on boyfriend Nico Jackson for wedding bells perhaps?

According to People, Pippa Middleton visited Amaia, one of the Duchess of Cambridge's favorite boutiques, located at Chelsea Green neighborhood.

"The doting aunt bought a Liberty print pink top with bloomers in a matching fabric and a cardigan," the article said. "She also bought a blouse with a frilly collar similar to the one she wears in her official portraits."

"Middleton - who recently unveiled several of her own designs for charity - chose the three-month size, which is the smallest size in Amaia stock, and remarked that she hadn't shopped sooner because her sister and brother-in-law didn't know whether they were expecting a little boy or girl," it added.

The wedding rumors involving Pippa Middleton and boyfriend Nico Jackson have been reported by the tabloids started in 2013. Obviously, the ceremony didn't push through, and it's getting harder even now her boyfriend took a job overseas.

Earlier this month, Life & Style magazine reported that Pippa Middleton and Nico Jackson are already engaged.

"Kate is so happy for Pippa and she loves Nico. They all get along so well!" the source said.

In fact, the Duchess of Cambridge even help picked the engagement ring.

"It will definitely be a stunner," the source said of the engagement ring to be given to 31-year-old Pippa Middleton.

The Irish Independent confirmed that there's going to be a wedding as Nico Jackson is ready to propose to Pippa Middleton.

"It's only fitting that Pippa's personal life would match her professional success as she has been enjoying yet another new career direction as she embarks on a nutrition course," it said.

"She has signed up her royal sister to a fresh juice delivery service and working on green smoothies for toddler nephew Prince George."
