Kaley Cuoco, "The Big Bang Theory" sweetheart aka Penny, makes it no secret that she's a fan of Jennifer Aniston. Interestingly, parallels may be drawn from their career and dating stories. Like Jen when NBC's "Friends" was still on air, Kaley is now one of the highest paid comedy actresses on TV - next to biggest earner Sofia Vergara.

In another "coincidence," both Kaley Cuoco and Jennifer Aniston had been with A-list celebs. The 1990s TV comedy icon married Brad Pitt. Kaley was with Man of Steel 2013 Henry Cavill albeit for only two weeks, as reports say.

Kaley was also in Picture Perfect (1996), which stars Jen Aniston and Kevin Bacon, among others. See Kaley's pronouncement of Jen love in this Instagram post:

As Rachel Karen Greene in Friends, Jen figures in an on again and off again relationship with Ross Geller (David Schwimmer). As Penny (last name still unknown) in The Big Bang Theory, Kaley is also in an unstable relationship with Johnny Galecki’s Leonard Hofstadter. (CREDIT: Glamour, Instagram)

As Rachel Karen Greene in Friends, Jen figures in an on again and off again relationship with Ross Geller (David Schwimmer). As Penny (last name still unknown) in The Big Bang Theory, Kaley is also in an unstable relationship with Johnny Galecki's Leonard Hofstadter. The difference here is that Kaley publicly came out she had a 2-year secret relationship with Johnny.

After briefly dating Superman Henry Cavill, Kaley quickly moved on to a new chapter. She's now dating tennis pro Ryan Sweeting, whom she had met on a blind date. Some reports cited unnamed sources who said Kaley was overwhelmed by the media attention during her dalliance with Superman. It seems the sassy comedy actress does not like being under the paparazzo's radar all the time.

Now Jennifer Aniston is getting married, while Kaley cancelled her engagement with Josh Resnik a year ago. The formerly engaged comedy actress did not reveal why she called off her wedding plans.

Kaley Cuoco was seen last week in Heidi Klum's "Project Runway." She came with another guest judge, Anne Fulenwider of Marie Claire. Aside from Klum, 'Runway' regulars are Nina Garcia and Zac Posen.

Thanks to its consistently high ratings, "The Big Bang Theory" is making Kaley Cuoco's name even bigger. It would not be surprising to see Kaley take on rom-com roles in the movies. Jennifer Aniston has had a few film hits, and Kaley may be on the same trail.

In TBBT Season 7, Kaley's Penny will be bonding with Jim Parsons' Sheldon Cooper. They both miss Leonard (Johnny Galecki) so much, so fans will be treated to their ways of coping with Leonard's absence.
