Oprah and best friend Gayle King are all smiles in pictures from their European vacation

Popular TV Show host and media mogul, Oprah Winfrey and her best friend Gayle King, appear to be having the time of their lives while enjoying their European Vacation.

King, garbed in a multi-colored gown with tiny straps, took to the ‘Gram to post a series of pictures featuring the duo as they went sightseeing. Oprah was spotted in a blue kaftan paired with white pants, and a matching white hat.

The pictures were soon trailed by tons of comments from followers who suggested places to visit, as well as the best photo locations.

Oprah and King's photographs showed how simple yet classy their European vacation was. They were joined at one point by fashion designer, Diane Von Furstenberg, and all three had a great time.

The media mogul, 64, recently raved about her picture-perfect year, describing the vacation as the “Summer of her life.'”

Meanwhile, King, “CBS This Morning” host and O Magazine editor-at-large credited J.C. Hayward as her biggest mentor in an interview last month. She recalled:

“In this business, J.C. Hayward from back in the day. When I was just a young pup as a production assistant at a CBS affiliate in Washington, D.C., she was very kind and very generous with her time to help me with my writing and help me with presentation. There was also Pam Coulter, who doesn’t remember it but was a CBS radio reporter who I also thought was very good, and I was her intern. She was very helpful. You don’t forget the people who were helpful to you when you were first starting out. It was funny – Pam Coulter worked at CBS TV and CBS Radio, and after I (started working for CBS), I called her just to say “oh my God, Pam, I’ve never forgotten you.”

When asked what advice she would give anyone willing to follow in her footsteps, King, 63, responded:

“Get your foot in the door and work your butt off. If that means taking an entry-level position, get your foot in the door and find somebody who you can tell is willing to help. In any organization, there’s always going to be somebody that doesn’t mind helping…”
