She returned to the studio in late 1946 to film The Shocking Miss Pilgrim with Dick Haymes. Set in the Victorian era, the public was not happy with a film that did not display Grable's legs (there were thousands of letters of protest), however the star's drawing power ensured the success of the film, which grossed 2.25 million dollars! Then it was back to tried and true formula with Betty appearing in Mother Wore Tights with Fox's newest lead Dan Dailey. The match proved to be very successful, the two had the right screen chemistry, leading this film to gross 4 million dollars. Betty and Dan became close friends and remained so for many years. Betty then took another break away from Fox to give birth to her second daughter, Jessica who was born on May 20th, 1947.

That Lady in Ermine was filmed later that year, and was not success at all. Betty was not enthusiastic for the part, nor was she impressed with her leading man Douglas Fairbanks, Jr. Her next film she was paired with Dan Dailey again in When My Baby Smiles At Me. Pairing her and Dan Dailey were always a successful match as the two worked extremely well together. Her next film was The Beautiful Blonde From Bashful Bend, another film Betty did not want to make. She did not feel at ease in this raucous film, and her reluctance was well founded as it was a flop in the box office. Then in the seesaw manner of her career, she was once again at the top in the re working of her previous film Coney Island, now titled Wabash Avenue, with Victor Mature and Phil Harris. It was the only time a star appeared in a remake of one of their own films, and for the same studio. In that same year, Dailey and Betty were paired yet again for My Blue Heaven, but Zanuck who was afraid that Grable's crown may soon slip, brought in a new signing, Mitzi Gaynor, making her film debut. The head of the studio was now scheming his way to ease Grable out of the studio. Then for the fourth and final time she and Dan were once again paired for Call Me Mister. Her next film shot in 1951 was Meet Me After The Show, (and is my personal favorite) but was difficult for Betty as there were some very strenuous dance numbers. When filming ended on this film Zanuck insisted she begin work on another film, which had similar dance sequences in it. She needed a rest, but Zanuck wouldn't let up. When she refused to do so, he put her on suspension for the second time.

There were two more pictures for Fox, The Farmer Takes A Wife and How To Marry A Millionaire (with Marilyn Monroe and Lauren Bacall) before Betty was suspended for a third and final time for refusing Zanuck to loan her out to Columbia for The Pleasure Is All Mine. Betty was finally fed up with Fox and Zanuck and in July of 1953 she walked into Zanuck's office, tore her contract up into little pieces and quietly said, "I'm leaving." Ironically, when the reviews for How To Marry a Millionaire came out in November of 1953, Betty was the one who received the best notices. She didn't care however, her relationship with Fox was over, well, not quite...she was approached directly by Columbia to appear with Jack Lemmon in the film she had earlier turned down, now re-titled Three for The Show. Then, much to her surprise, a call from Zanuck, would she be interested in doing How To Be Very Very Popular (a part which Monroe had turned down). Her answer was "Yes, for a price." She received top billing over Sheree North, the new budding starlet Fox was trying to promote over their unwilling "other blonde" Marilyn Monroe, but Betty really didn't like the film, and neither did critics. It did not do well when it was released in July 1955. Betty was not concerned, her love affair with Hollywood was over.
