Regex issue for getting second group from string

Question

I tried with below Regex

Input string = \nAddress 123 Abc st. Phone (123) 456-7890\nLine2\nLine3\nCity";

Regex

Regex rg = new Regex(@"Address(.*)Phone.*\n(.*)City", RegexOptions.Singleline);

But when I have used given regex at that time in the output I got below result set.

for first group = 123 Abc st. for second group = null.

My expected output is as below but from above regex, I got only result set one but not the second one.

expected output

Group 1 = 123 Abc st.

Group 2 = Line2\nLine3
