Reduce space between List of Figures and List of Tables entries in Table of Contents

I have quite a long Table of Contents in which I first add the entries for List of Figures, List of Tables, and Abbreviations. However, the entire toc goes over one page. Thus, I would like to reduce the space between the first three entries (lof, lot, abb) to 1 (instead of the 1.5 that I use for the rest of the document/toc. Any idea how to solve this for only these three entries?
This is my MWE:

documentclass[12pt, a4paper]{article}
usepackage[paper=a4paper,left=3cm,right=2.5cm,top=2.5cm,bottom=2.5cm]{geometry}
usepackage[american]{babel}
addtocaptionsamerican{
  renewcommand{contentsname}%
    {Table of Contents}%
}

usepackage{acro}
DeclareAcronym{x}{
  short = X ,
  long  = {X} ,
  class = abbrev
}

usepackage{fancyhdr}
setlengthheadheight{14.49998pt}
pagestyle{fancy}
rhead{thepage}
lfoot{}
cfoot{}
rfoot{}

linespread{1.5}
