Jon Lovitz in "Sing Your Face Off" on ABC.ABC goes all in for a Saturday night reality show summer, with the return of the lowly “Bet on Your Baby” (ABC, 8 p.m.), because they’re more fun than turtle races; and the premiere of “Sing Your Face Off” (ABC, 9 p.m.), in which celebrities not only perform the songs of their musical heroes, they dress up as them as well. For two hours! Among them is former Skid Row singer Sebastian Bach, who dresses up as both Adam Levine and Lady Gaga. Not enough? How about Jon Lovitz as Elton John and Pavarotti, or Lisa Rinna as Dolly Parton and Britney Spears? No, I didn’t think so.

John Barrowman is the host of the show that is a knock off of the British “Your Face Sounds Familiar.” Its judges are Debbie Gibson and “SNL” alum Darrell Hammond.

Because of the annual “Rock and Roll Hall of Fame Induction Ceremony” (HBO, 8 p.m.), there is a pronounced lack of premium cable movie premieres tonight. But there are a couple of made for cable romances of different stripes.

In “The Color of Rain” (Hallmark, 9 p.m.), Lacey Chalbert, once of “Party of Five,” stars as a young woman who loses her husband after a long illness, only to find another man in her church community who suddenly lost his wife to cancer, portrayed by Warren Christie. It’s about as wholesome and slow moving a courtship and blending of their families as you’d expect, with the result you will also completely expect. That makes it reassuring in a way, and nearly crisis-free.

In a strikingly different approach, the sufficiently sensual Ashley Jones of the soon to return “True Blood” stars as a divorced woman who goes the “Fifty Shades of Grey” route in the purposely seedy “The Secret Sex Life of a Single Mom” (Lifetime, 9 p.m.) opposite the dominant Alex Carter, who calls himself The Duke. The promos misleadingly insist it’s “based on the book that fueled a phenomenon,” showing a bolt of grey. But it’s really based on a Canadian book by Delaine Moore.

Imagine the coin flip between Brian Williams and Matt Lauer: Heads, Edward Snowden interview. Tails, Mariah Carey. Lauer, who must have come up short, goes to the Hollywood Hills for the prime time interview: “Mariah Carey: At Home in Concert with Matt Lauer” (NBC, 8 p.m.). That doesn’t mean the “Today” host sings. Instead he talks with the singer and her husband, Nick Cannon, who just happens to host “America’s Got Talent” for the network. Suggested first question: Why did you name your twins Moroccan and Monroe? Wouldn’t Madison have been the smarter choice?

“48 Hours” (CBS, 10 p.m.) talks with the woman who was stabbed 32 times by an ex-boyfriend and lived to face him in court.

Discovery networks are starting to lure stars from their actual reality shows to get them involved in their increasingly fictional quests. Two aptains from Deadliest Catch,” Johnathan and Andy Hillstrand are dispatched to Homer to look for a Loch Ness type creature in “Alaskan Monster Hunt: Hillstranded” (Discovery, 7 p.m.).

It’s a little offensive that they chose as host of a “Mini Monsters” (Discovery, 9 p.m.) special about chipmunks, beetles and tiny marmoset monkeys, the actor Peter Dinklage.

An Ottoman empire attack is imminent on “Da Vinci’s Demons” (Starz, 9 p.m.).

Alison worries about being exposed by someone in rehab on a new “Orphan Black” (BBC America, 9 p.m.).

“We Should Have Eloped!” (TLC, 10 p.m.) sounds like the natural thing to follow “Sex Sent Me to the ER” (TLC, 8 and 9 p.m.).

Julie Andrews, Channing Tatum, Jonah Hill and Pharrell Williams are guests on “The Graham Norton Show” (BBC America, 10 p.m.).

Pygmalion stories are the theme on Turner Classic Movies. And though they don’t include the Shaw play, there is its most famous adaptation, “My Fair Lady” (8 p.m.), followed by “Princess Tam Tam” (11 p.m.) and “Born Yesterday” (12:30 a.m.).

In Game 6 of the NBA Western Conference Finals, it’s San Antonio at Oklahoma City (TNT, 8:30 p.m.).

Baseball includes the prime time Pittsburgh at Dodgers (Fox, 7 p.m.) as well as Minnesota at Yankees (MLB, 1 p.m.), Atlanta at Miami (Fox Sports 1, 4 p.m.) and Detroit at Seattle (MLB, 10 p.m.).

Third round action continues in the French Open (Tennis Channel, 5 a.m.; NBC, noon).

Miranda Lambert plays a replay of “Austin City Limits” (PBS, 9 p.m., check local listings).

The Charlize Theron-hosted “Saturday Night Live” (NBC, 11:30 p.m.) with the Black Keys is rerun.
