Louis Tomlinson of "One Direction" is reported to be demanding a DNA test for Briana Jungwirth's baby as soon as she gives birth. Apparently, the first baby-mama of the group may or may not be Louis' baby mama after all, as her pregnancy may be blamed to someone else. According to reports, there are high chances that Briana isn't carrying Louis' baby as she was sleeping with a different guy before her pregnancy.
