Prince William and Kate Middleton continue to receive praises from royal fans and experts. Whether it may be for their work or their characters, they almost always obtain the love and adoration of the public.

A relationship expert recently shared a different form of praise toward the Duke and Duchess of Cambridge. Speaking to the Daily Express, Sami Wunder commended the royal couple for their marriage and ties.

She said that they "exemplify" a strong power pair. She even called the future British Monarch and his Queen Consort the "ultimate royal power" duo.

Wunder explained that Kate Middleton and Prince William are "solid" on many levels. She added they are a "perfect team" not only in their duties and responsibilities as senior working royals but, also, in their roles as a married couple and parents to their three children.

The expert continued that the Duke and Duchess have a "strong connection" because of their ties that they established since their university days. She, then, asserted that they have seemingly maintained this connection throughout their marriage and the birth of their children.

In the end, Sami Wunder asserted that they are an "unbreakable couple." They could even be a "blueprint" for other royal couples, like Meghan Markle and Prince Harry.

The relationship expert did not, however, make any comments about the Sussex couple's relationship. Nevertheless, she pointed out that the Duchess of Sussex has a "voice" of her own, noting that she is a "strong woman."

Wunder, later on, stated that the former actress does not need her husband to complete her. She countered, though, that Prince Harry is not less of an "empowered man."

 Meanwhile, Hello! magazine released a timeline of Kate Middleton and Prince William's relationship since their engagement. This comes after commemorating the announcement of their engagement in November of 2010.

The outlet released ten photos of the Cambridge couple, showing how things have changed between them in the last decade. Most of the photos featured their relationship milestones, including the birth of each of their children, as well as their first trips together, alongside the young royals.

The latest photo shows Kate Middleton and Prince William during their "romantic stroll" in Ireland earlier this March. It marks a month before their ninth wedding anniversary in April.

These days, the Duke and Duchess of Cambridge remain active and dedicated to their roles within the British Monarchy. Many experts believe that they continue to step-up with their duties and responsibilities, causing more individuals to praise them for their "unwavering" commitment.
