Pippa was most recently seen enjoying an afternoon lunch with her ex, James Matthew, this past weekend. If that weren't enough, she was also seen getting up close and personal with another former beau of hers, Alex Loudon, last month.

According to the Daily Mail on Tuesday, Pippa and Matthew were caught by the paparazzi going into a house in West London last week after walking the investment banker's dog. Back in September, she was also reportedly seen going on a shopping spree with Loudon, too.

Even though she's been getting very chummy with her ex-boyfriends lately, she is still linked to her boyfriend Nico Jackson, even though he's been living full-time in Geneva, Switzerland while she's back in London. Rumor has it that the couple might be on the brink of a breakup, as the distance between them has proven to be a huge strain on their relationship.

Many of Pippa's fans think it's time to move on, as Jackson's opportunity to make their relationship official has definitely expired.

One commenter wrote, "What is Nico Jackson waiting on, to propose? An invitation by royal command? They've been going out for 2 years, already - she's 32, either put a ring on it or get moving. Typical modern day, 'man', wasting her time," while another said, "Looks like she's putting the pressure on her boyfriend to propose. Taking her mother's advice no doubt, same as she gave Kate. Show him you have options, and a lot of them, and then wait for him to finally act and take you off the market."

Another critic wrote, "There is a difference between being friends and trying to hold on to people, as if you are keeping your options open. It's fine if you are single but if she's in a relationship it's disrespectful and seems to be a grab for attention."
