Best Bets: "The Bachelor," "Fashion Star," SXSW and "21 Jump Street"

Bachelor Ben Flajnik examines the diamond ring he will bestow on one contestant tonight on "The Bachelor."

(CBS News) There will be a marriage proposal on bended knee tonight when California winemaker Ben Flajnik chooses a soulmate on the finale of ABC's "The Bachelor."

For TV viewers, this week is a season midpoint when shows like "The Bachelor" wind up, to be replaced by new offerings like "Community," which returns to NBC on Thursday.

NBC is also serving up a new reality show called "Fashion Star" on Tuesdays. Supermodel Elle Macpherson hosts the show with Jessica Simpson, Nicole Richie and John Varvatos, serving as mentors to aspiring designers trying to market their work to buyers. What makes this show different from some of the others like it, NBC says, is that the designs will be available in stores the very next day.

ABC's new offering is "Missing," a drama in which Ashley Judd plays a widow searching for her missing 18-year-old son. It airs on Thursdays.

AMC's zombie hit "The Walking Dead "  ends its second season on Sunday night to make way next week for "Mad Men."

It's also a big week for music lovers with the five-day SXSW festival opening in Austin on Tuesday. John Mayer has pulled out because of recurring vocal cord problems but the Ting Tings, Talib Kweli, and Built to Split are all expected to perform.

Those who remember the Johnny Depp TV series of the 1980s may be eager to see the big-screen adaptation of "21 Jump Street" starring Johan Hill and Channing Tatum. It opens on Friday, as does "Jeff Who Lives at Home," a comedy starring Jason Segel, Ed Helms and Judy Greer.

More Oscar nominees are coming to the small screen this week. DVD releases Tuesday include "The Descendants," "Melancholia," "A Dangerous Method" and "Happy Feet Two."

"Third Rock from the Sun" actress Kristen Johnston tells about her life and career, including a battle with substance abuse, in her memoir "Guts," which is due out on Tuesday.

Among the other books due out that day are "Acadia," by Lauren Groff who wrote "The Monsters of Templeton" and "The Vanishers," a novel by Heidi Julavits.
