There's no denying that the two teenagers look just like their father -- from their noses to their smiles, it looks like they inherited a lot of Larry's genes.

17. Anderson Cooper: $9 million to $11 million
Cooper has been hosting his CNN show "Anderson Cooper 360" since 2003.
It pays to move to Netflix. The former E! host reportedly signed a $10 million deal with Netflix consisting of several comedy specials and a talk show for the streaming service. Handler previously made between $8 million and $12 million for her E! show.
The "Good Morning America" cohost received a big pay bump in the last few years. In 2013, it was estimated she made $6 million per year. Roberts has been an anchor on "Good Morning America" since May 2005.
12. Conan O'Brien: $12 million
O'Brien's switch to TBS has proved more profitable than some of his late-night network competition. He has been hosting "Conan" since 2010 on the network. In May 2014, O'Brien signed a deal to stay on TBS through 2018.
11. Pat Sajak: $12 million
In 2013, Sajak told The Huffington Post he may be nearing the end of his time hosting the game show "Wheel of Fortune." But his time at the wheel isn't over just yet. Last year, Sajak renewed his contract through the 2017-2018 season.
Kelly is set to make $15 million in her last year at Fox News. The cable news network reportedly offered her more than $20 million to renew her contract. Despite being courted by rival news organizations, including NBC News, it became clear that they could not match Fox News' money, according to the The New York Times.
That likely means that NBC lured over Kelly with a broad, multi-year deal that would make her a star on its broadcast network — and hence give her a wider audience — with a salary landing between $15 million and $20 million.
5. Kelly Ripa: $16 million to $20 million
Ripa took over hosting duties on "Live!" in 2011 after the departure of Regis Philbin and is currently searching for a new cohost after Michael Strahan's recent exit to host on "Good Morning America" in April.
