Most normal 25-year-olds are free to navigate the young adult dating scene without their every move being scrutinized or speculated upon. Jana Duggar, however, is not a normal 25-year-old.

Jana is famous for being the oldest daughter of the Duggar clan, which is the star family in the TLC reality series 19 Kids and Counting!;. While her younger sisters Jessa and Jill have gotten hitched (and the latter expecting a first child), Jana has remained single and untethered throughout her time in the limelight.

Tim Tebow, Jana Duggar Deny Dating Rumors

Numerous outlets in December linked Duggar to Heisman Trophy winner Tim Tebow. The hypothetical coupling seemed to make sense -- Jana's father Jim Bob is friends and philanthropic partners with Tebow's mother Pam, and both Tim and Jana were rasied in conservative Christian environments. However, the dating rumors ultimately seemed to be unfounded.

Since December neither Duggar nor Tebow has been linked to any other prospective beaus or belles.

"The problem is that Jana's extremely picky," sources close to the Duggar family told MStarz recently. "She wants the real deal and won't settle for less."
