That's My Baby.

On the eve of his wedding, businessman Alan Boyd gets a telegram notifying him that his "bride" has fallen in love with another man and eloped with him. Announcing that he is through with women, an hour he meets pretty Helen Raynor, who takes to him (and is also his business rival's daughter). Helen's mother, though, doesn't take to Alan at all. In addition, Schuyler Van Loon, who is also after Helen, comes up with a scheme to embarrass Alan in Helen's eyes and ruin his reputation in the bargain--he comes up with a "baby" he claims is Alan's illegitimate son.
